Question

Y intercept of y=2(4×)

Answer 1

y=intercept at y = 2

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

Edit: spelling correction

Answer 2

The y-intercept for this function is y = 2

(0, 2)

Explanation:

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

Put x = 0 to y = 2(4ˣ):

`y=2(4^0)` we know a⁰ = 1

`y=2(1)`

`y=2`
