Hey! can you please do these 5 questions correctly? Thanks and i need answers ASAP :)) (will give 20 points and brainliest)

Heather is writing a quadratic function that represents a parabola that touches but does not cross the x-axis at x = -6. which function could heather be writing? fx) = x2 + 36x + 12 = x2 - 36x - 12 f(x) = -x + 12x + 36 f(x) = -x? - 12x - 36

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30

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.
