Card 1 of 22

What condition must (p,q)(p,q)(p,q) satisfy to lie on y=f(x)y=f(x)y=f(x)?

A

Solve ax+b=0ax+b=0ax+b=0; the vertex is (x,0)(x,0)(x,0).

B

The graph of y=ax2y=\frac{a}{x^2}y=x2a​ is symmetric about the yyy-axis because replacing xxx by −x-x−x does not change x2x^2x2.

C

q=f(p)q=\boldsymbol{f(p)}q=f(p)

D

The graph of y=kxy=kxy=kx is a straight line through the origin with gradient k\boxed{k}k​.
