Answer:

The y-intercept for this function is y = 2

(0, 2)

Step-by-step explanation:

y-intercept of f(x) is value of y for x = 0.

Put x = 0 to y = 2(4ˣ):

[tex]y=2(4^0)[/tex]    we know a⁰ = 1

[tex]y=2(1)[/tex]

[tex]y=2[/tex]

Answer:

y=intercept at y = 2

Step-by-step explanation:

Assuming that the equation presented is

y = 2(4ˣ)       (i.e  NOT y = 2(4x)  )

The y - intercept occurs when the graph intercepts the y-axis at x=0.

Hence we simply substitute x=0 into the equation

y = 2(4ˣ), for x=0

y = 2(4⁰)

y = 2.

Hence the y-intercept occurs at y=2

Alternatively, you can simply plot the graph and see where it crosses the y-axis. From the attached, we can see that the y-intercept is y=2
