f(x) is an exponential function with these features: f(x) is increasing, the y -intercept is (0,1) , and f(2)=49 . Which function could be f(x) ?(1 point)

Answer 1

The function that fits these criteria is f(x) = 1 * 7^x.

To verify:
- f(x) is increasing because the base of the exponential function is greater than 1.
- The y-intercept is (0, 1) because when x = 0, f(0) = 1 * 7^0 = 1.
- f(2) = 1 * 7^2 = 49.

Therefore, f(x) = 7^x could be the function that satisfies the given conditions.
