# Math Help - [SOLVED] SAT math 683 #14

1. ## [SOLVED] SAT math 683 #14

Again, I am cramming the SAT math. Any helpful replies for my threads are greatly thanked and appreciated! Thanks

If the function f is defined by f(x)=x^2=bx+c, where b and c are positive constants, which of the following could be the graph of f?

I already eliminated a) and b) since i can tell from the function that a is positive so it has to be concave up. (a and b where both graphs which where concave down) (:

(Sorry for the sloppy graphs)
