• Exponential

• Neither

What type of function is this equation:
y=  4^x+1

• Linear

• Exponential

• Neither

Is the table linear, exponential or neither?

• Linear

• Exponential

• Neither

Given y=4^(x+1) determine the y-intercept.

• (0,1)

• (0,4)

What is the y-intercept for all the exponential mother functions such as y=2^x, y=3^x, and y=4^x?

• y=1

• y=0

• y=2

• y=4

To find the Y-intercept of a Exponential Function, we set X= 0 and solve.

• TRUE

• FALSE

Answer explanation
