Question

What is the y-intercept of the graph of the equation y=4(3^x)?

Answer 1

4, or (0, 4)

Explanation:

Set x = 0 and evaluate y=4(3^x): y(0) = 4(3^0) = 4(1) = 4.

The y-intercept is 4, or (0, 4).

Answer 2

The y-intercept is (0, 4).

Explanation:

At the y-intercept x = 0 so

y = 4(3^0)

y = 4*1 = 4.

So the y-intercept is (0, 4).
