PLEASE HELP IF ANYONE KNOWS HOW TO DO THIS PLEASE HELP! Given the function:
f(x) = -2° + 2x² - 4

a) Explain how to evaluate f(-4). Include the value in your description.

b) Explain how to evaluate f(-3). Include the value in your description.

C) True or False? A zero of f(x) lies on the interval (-4,-3). Explain how you came to this conclusion.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

explanation:

remove parenthesis:

=

apply rule
