Find the equation of the line and plug in the x value that gives you which is -3? i am not very sure so i am sorry if i am wrong
A formula helps you or tells you what to do to find the are, perimeter, volume of any shape. A = 1 x w is a formula to find an area of a 2-d figure. it is a formula becuase it tells you what to do to find the area.
f(x) = 5x − 1 and g(x) = 2x^2 + 1
(f × g)(x) = (5x − 1)(2x^2 + 1)
(f × g)(x) = 10x^3 - 2x^2 + 5x - 1
Substitute x = - 3
(f × g)(-3) = 10(-3)^3 - 2(-3)^2 + 5(-3) - 1
(f × g)(-3) = 10(-27) - 2(9) -15 - 1
(f × g)(-3) =-270 - 18 - 16
(f × g)(-3) = -236
Answer
- 236
