Answer:

LEts start with 10^1

If we have positive exponent then we add zeros

10^1= 10

10^2=100 (Put 2 zeros because exponent is 2)

10^3=1000 (Put 3 zeros because exponent is 3)

10^4=10000 (Put 4 zeros because exponent is 4)

10^5=100000 (Put 5 zeros because exponent is 5)

For negative exponent , we make a fraction . we put 1  at the top always and number as the bottom

10^{-1}=\frac{1}{10} (Put 1 zero at the bottom because exponent is -1)

10^{-2}=\frac{1}{100} (Put 2 zeros at the bottom because exponent is -2)

10^{-3}=\frac{1}{1000} (Put 3 zeros at the bottom because exponent is -3)

Question 4 (1 point)
mrs_skeptik [129]

Answer:

(C)y=0

Step-by-step explanation:

An exponential function of the form f(x) = a (b^x) + c always has a horizontal asymptote at y = c.

Given our function y=4^x

Comparing with the form,  f(x) = a (b^x) + c, we observe that c=0.

Therefore, the exponential function has an <u>asymptote at y=0.</u>

The correct option is C.
