-15 degrees = -15 pi / 180 = -pi/12 radians
convert 7pi/6 to degrees
= 7pi/6 * 180 /pi = 210 degrees which is in Quadrant III
1,5,7,35
Here is your answer--☝️☝☝☝
F(x) = 3x + 7.....g(x) = 4x - 2
A. (f + g)(x)
3x + 7 + 4x - 2
7x + 5 <====
B. (f * g)(x)
(3x + 7)(4x - 2) =
3x(4x - 2) + 7(4x - 2) =
12x^2 - 6x + 28x - 14
12x^2 + 22x - 14 <===
C. f[g(x)]
3(4x - 2) + 7 =
12x - 6 + 7 =
12x + 1 <===
