Given the function f defined by the formula f(x)=x^2-4 find the following: (a) f(3) (b) f(-4) (c) f(0) (d) (-2)

f(x) = x² - 4

f(3) = 3² - 4 = 5

f(-4) = (-4)² - 4 = 12

f(0) = (0)² - 4 = -4

f(-2) = (-2)² - 4 = 0

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
