For the functions f and g find (only need help with one qustion) a. (f+g)(x),
b. (f-g)(x),
c. (f. g)(x)
d. (f/g)(x)
f(x) = x-3, g(x) = 8x + 5 (x).
a. (f+g)(x) = 9x + 2
b. (f-g)(x) = -7x-8
c. (•g)(x) = 8x2 - 19x - 15
d. (f/g) (x)= ◻​

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

36.75 because 21/4 = 5.25 and 36.75/7 = 5.25
