Question

For each Graph:

A. Match the graph with the correct equation
B. Explain how you made your match

Answer 1

Zôzzozoso hey this is my answer

Answer 2

a) B

b) D

c) C

d) A

Explanation:

a)

The graph is of a decay function, so the base of the exponential is less than 1. The only choice is B, y = 2(1/2)^x.

__

b)

The graph is a reflection across the x-axis, so the leading multiplier is negative. The only choice is D, y = -2^x.

__

c)

The y-intercept is less than 1, so the leading multiplier will be less than 1. The only choice is C, y = 1/2(2^x).

__

d)

The y-intercept of this growth function is 2, so the leading coefficient is 2 and the growth factor is greater than 1. The only choice is A, y = 2(2^x).
