Question

With exponential functions of the form y= -a • b -x , as x goes to negative infinity , the y- values tend towards______.

Answer 1

-∞

Explanation:

You want the limit of y = -a(b^-x) for a, b > 0 as x → -∞.

End behavior

A normal exponential function with a positive multiplier 'a' will tend toward infinity as x gets large. When the function is reflected over the y-axis by replacing x with -x, the function will tend toward infinity when x goes to large negative numbers.

When the sign of the function value is reversed by making 'a' < 0, the y-values tend toward negative infinity when x goes to negative infinity.
