Answer:
See below.
Step-by-step explanation:
Plot some points:
y = 4^x
When x = 0 y = 4^0 = 1 so the graph passes through (0,1).
x = 1, y = 4^1 = 4 so it passes through (1,4).
You can plot a few more points for x = 2 and x = 3 . You'll see that the graph rises at a fast rate for positive values of x.
When x = -1 , y = 4^-1 = 1/4
x = -2 , y = 1/16
x = -3, y = 1/64
Thus, for negative values of x, the values of y rise slowly from close to y = 0 to meet the y axis at y = 1. When x approaches negative infinity y is very close to 0 but never is 0.
