The zeros of the function are , 3, and , and the y-intercept of the function is located at .

The zeroes are -1, 3, and -2

The y intercept is located at (0,6)

Step-by-step explanation:

(x+2)=0

x=-2

The easiest way is to use an online graph like desmos and graph the problem there. You can see where the y intercept is.

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.

the answer for your question is
