Find the quadratic function f(x) = ax + bx+c that goes through (5,0) and has a local minimum at (0, -1). f(x)=

Iknow one of the answers is a and maybe b but not 100% sure about b

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.
