Which function, g or h, is the inverse function for function ƒ? the function h because the graphs of ƒ and h are symmetrical about the line y = x

the function g because the graphs of ƒ and g are symmetrical about the line y = x

Neither function is the inverse function for function ƒ.

the function g because the graphs of ƒ and g are symmetrical about the y-axis

it is not that hard all u have to do is plot the graph

step-by-step explanation:

c

-by-step explanation:

it would be c

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
