An exponential function is written as f(x) = a • bx, where the coefficient a is a constant, the base b is but not equal to 1, and the exponent x is any number

Constant.

For example:

3×(2)^ x  and 3×(80)^x are two different exponential functions.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
