10-105.

Match each equation below with its corresponding graph. Can you do this without making any tables? Homework Help ✎

a.

*y =*2– 1^{x}b.

*y =*2+ 3^{x}c.

*y =*2+ 2^{x}1)

2)

3)

Consider the *y*-intercept for each function.

Considering equation (a). The *y*-intercept is calculated by letting *x* = 0.

So *y* = 2^{0}−1 so *y* = 0 when *x* = 0.

Which graph has (0,0) on it?
