PLEASE HELP Determine if the function f is an exponential function. If so, identify the base. If not, why not? f(x)= (-1/4)^x-3.141

A) This is not an exponential function because the base must be a positive value.

B) This is a polynomial.

C) The base is −4−1.

D) The base is 3.141.

The function f has a an exponent which is the variable ( the letter x) therefore it is an exponential function.

The base is the number being raised by the exponent ( -1/4)

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
