## What is the graph of exponential function?

The graphs of exponential functions are nonlinear—because their slopes are always changing, they look like curves, not straight lines: Created with Raphaël 1 \small{1} 1 2 3 4 -1 -2 -3 -4 1 2 3 4 5 6 7 -1 y x O y = 2 x + 1 \purpleD{y=2^x+1} y=2x+1. You can learn anything. Let’s do this!

### What are the characteristics of the graphs of logarithmic functions?

Characteristics of Logarithmic Functions Graphs

- The graph of logarithmic functions passes through the points (1,0).
- If the base of a logarithmic function is greater than 1, then the graph increases.
- If the base of the logarithmic functions is greater than 0 but smaller than 1, then the graph decreases.

#### What is the difference between logarithmic and exponential graphs?

Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. y = logax only under the following conditions: x = ay, a > 0, and a≠1.

**How do you tell the difference between an exponential and logarithmic graph?**

As you can tell from the graph to the right, the logarithmic curve is a reflection of the exponential curve….Comparison of Exponential and Logarithmic Functions.

Exponential | Logarithmic | |
---|---|---|

Function | y=ax, a>0, a≠1 | y=loga x, a>0, a≠1 |

Domain | all reals | x > 0 |

Range | y > 0 | all reals |

**What is the difference between exponential and logarithmic graphs?**

## What are exponentials and logarithms?

Logarithms are the “opposite” of exponentials, just as subtraction is the opposite of addition and division is the opposite of multiplication. Logs “undo” exponentials. Technically speaking, logs are the inverses of exponentials.

### What is the relationship between the graphs of exponential and logarithmic functions?

We can see the relationship between the exponential function f(x) = ex and the logarithm function f(x) = ln x by looking at their graphs. You can see straight away that the logarithm function is a reflection of the exponential function in the line represented by f(x) = x.

#### What is the difference between exponentials and logarithms?

Exponential (indices) functions are used to solve when a constant is raised to an exponent (power), whilst a logarithm solves to find the exponent. Both exponentials and logarithms have their own rules that you need to use.

**What is an exponential graph?**

An exponential graph is a graph of the function y=a^ {x} for some a>0. They all have the same basic shape. If a>1 then y increases as x increases. If a<1 then y decreases as x increases. Larger a gives faster increase if a>1 while smaller a gives faster decrease if a<1.

**What is the form of a general logarithmic equation?**

UNDERSTANDOne form of a general logarithmic equation is 5y alog [b(x2h)] 1k. The parameters involved, a, b, h, and k, have different effects on the function’s graph. The parameter hproduces a horizontal translation of the graph by hunits.

## What are logarithms and why are they used?

Logarithms, or logs for short, are the inverse of exponential functions and are used when we do not know what the exponent (power) is. Logarithms are written in the form to answer the question to find x . a is the base and is the constant being raised to a power.
