The equation is


f(x)=4^x

This is an exponential equation, we just keep multiplying each value by 4 to get the next value.

Thus the common ratio is 4.

ii. The y-intercept is the point the graph cuts the y-axis, also the point where x = 0. Putting x = 0, into the equation, we obtain.


f(x)=4^0=1

Thus, the y-intercept is (0, 1 )

iii. The horizontal asymptote.

The horizontal asymptote is the horizontal line the graph approaches.

Since the function is an exponential one. with zero y-intercept.

The horizontal asymptote is the line


y=0

Or the x-axis.

Therefore, The horizontal asymptote is the line y = 0
