Find where the lines y =-3x + 2 and y = 5x 6 cross in the coordinate plane.

Given f(x) = x − 7 and g(x) = x2 . find g(f( g(f(4))

Given: f(x) = 2x + 5 and g(x) = x2 and h(x) = -2x h(g(f( = x2+ vx+ x + y

Aclassmate thinks that solving a system by graphing gives an exact answer when the lines appear to cross at a grid point, but only an approximate answer when they don't. explain why this isn't true.
