If f(x) is an odd function, which statement about the graph of f(x) must be true? It has rotational symmetry about the origin. It has line symmetry about the line y = –x. It has line symmetry about the y-axis. It has line symmetry about the x-axis.

Step-by-step explanation:

it has line symmetry about x-axis

It has line symmetry about x-axis

x+14

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
