I don't understand this problem and how it equals 1 (attached). I thought if -3 =-x squared it would be 3*3 and then plus 5. I cannot think of a way to make this 1. What am I doing wrong?

f(2) = 1

f(-3) = 4

Step-by-step explanation:

We are given the function:

To evaluate the function, substitute the number in.

Evaluate f(2)

Evaluate f(-3)

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
