What is the range of the function f(x) = 4x + 9, given the domain d = {-4,-2,0.2}?
a. r = {1, 7, 9, 17}
b. r=(-17, -9,-1, 17}
c. r = {-7, 1, 9, 17}
d. r = {-7,-1, 9, 17)

The answer is C = {-7, 1, 9, 17}

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
