Let f(x) = 2x - 1 and g(x) = x2 + 5.
find (fog)0).

3x^2 - x^2 - 5

Step-by-step explanation:

since f(x) = 2x - 1 and g(x) = x^2 + 5

((2x - 1)(x^2+5)) multiply

3x^2 - x^2 - 5

faster, im not sure why but i know it is faster

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
