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 length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
