Question

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

Answer 1

y = -ab^-x , assuming x goes to negative infinity

If x assumes negative infinity, that means we will have b^-(-x) which is equal to b^x, which gives us a result of positive infinity.

If this positive infinity is multiplied then to -a, then the y-values tend towards negative infinity.

The answer is Option A.
