Let g(x)=x²-4x-42. Find x such that (x,3) is on the graph of g(x). OA. x=-9 or x = 5 B. x=-5 or x=9 OC. x=9 D. There is no such value of x.

Graph f(x)=x22x+3 by using its properties.

The rate of change of an autocatalytic chemical reaction is kQxkx2 where Q is the amount of the original substance, x is the amount of substance formed, and k is a constant of proportionality. Factor the expression.

For the fallowing exercises, find the x- and y-intercepts of the graphs of each function. 11. f(x)=2x+1+6
