1.2.9 Algebra and Functions

Card 1 of 20

How is the yyy-intercept of y=f(x)y=f(x)y=f(x) found?

A

Because replacing xxx by −x-x−x does not change x2x^2x2, y=ax2y=\frac{a}{x^2}y=x2a​ is symmetrical about the yyy-axis.

B

The graph of y=axy=\frac{a}{x}y=xa​ has rotational symmetry of order 2 about the origin.

C

The left end rises and the right end falls.

D

Substitute x=0x=0x=0.
