Below is the graph of y=b^x. find b.

Functions can be represented as equations, and equations can be represented as functions.

The value of b is 1/2

The graph is given as:

From the graph, we have the following point:

(x,y) = (-1,2)

Substitute these values in the function

Rewrite as:

Multiply both sides by b

Divide both sides by 2

Hence, the value of b is 1/2

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
