Step-by-step explanation:

To find out y intercept of any function, we plug in 0 for x and solve for y

For any function y=ab^x + c

The horizontal asymptote at y=c

Now we check each function

Plug in 0 for x to find y intercept

y intercept at (0,-3)

Horizontal asymptote at y=c , here c= -4

So horizontal asymptote at y = -4 and y intercept at (0,-3)

Plug in 0 for x to find y intercept

y intercept at (0,13)

Horizontal asymptote at y=c , here c= 4

So horizontal asymptote at y = 4 and y intercept at (0,13)

Plug in 0 for x to find y intercept

y intercept at (0,5)

Horizontal asymptote at y=c , here c=-4

So horizontal asymptote at y = -4 and y intercept at (0,5)

Plug in 0 for x to find y intercept

y intercept at (0,5)

Horizontal asymptote at y=c , here c= 4

So horizontal asymptote at y = 4 and y intercept at (0,5)
