Question

9.

Match the graph of the function with the function rule.

A. y = 1 • 4x
B. y = 2 • 4x
C. y = 3 • 10x
D. y = 10 • 4x

Answer 1

D. y = 10 • 4x

Explanation:

Answer: As seen from the graph, the y intercept is (0,0.5)

plugging this value in each equation:

y=1*4^x

plugging x as 0 and y as 0.5

lhs≠rhs

plugging x as 0 and y as 0.5

lhs = rhs

y= 1/2 x 4x

Answer:

D) y= 10*4^x

Step-by-step explanation:

Replace each function with x = 0

A)

B)

C)

D)

If you check the graph with x = 0, the value of y is between 8 and 12 so the only probably answer acoording to the alternatives is D) which gives y = 10 when x = 0
