The function f(x) = -5x2 + 3 is
defined over the domain
-4 < x < -1. find the range of
this function.
.
a. -77 < f(x) < -2
b. 8 < f(x) < 83
c. 8 < f(x) < 23
d. 8 < f(x) < 83
.
.

A. -77 < f(x) < -2

Step-by-step explanation:

- 4 < x < -1 so : (-1)² < x² < (-4)² because  f is decrasing if - 4 < x < -1

1< x² < 16now multiply by : -5

-80 < - 5x² < -5   add 3  you have : -77< - 5x²+3 < -2

-77 < f(x) < -2

i am sure it will be 90 degrees.
