Page 112 question 7 part c which equation matches the following graphA f(x)=2^xBf(x)=-2^xCf(x)=3x2^xDf(x)=-3x2^x

Answer 1

Given:

We get the point (0,3) which is lie on the graph from the graph.

Aim:

We need to find the equation of the given graph.

Step-by-step explanation:

The graph of the equation is growing upward.

The given graph is an exponential growth function.

Consider the eqaution of the exponential growth function.

`f(x)=a*2^x`

Substitute x=0 and f(3)=3 in the equation.

`3=a*2^0`
`a=3`

Substitute a=3 in the equation.

`f(x)=3*2^x`

Final answer:

`f(x)=3*2^x`
