If f(x) = x^4 + 3x^3 – x^2 + 6, find f(-3). A) -3 B) -2 C) 2 D) 3

f(-3) = -3

Step-by-step explanation:

replace x with -3 and solve

(-3)^4 = 81

3(-3)^3 = -81

(-3)^2 = 9

6 = 6

now solve

x^4 + 3x^3 – x^2 + 6

81 + (-81) - 9 + 6

-9 + 6

-3

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

step-by-step explanation:

it's 15
