When graphing the function f(x) =
x2-11X+ 18 on your graphing calculator, what is the most appropriate viewing window
for determining the domain and range of the function?
Xmin: -10, Xmax: 10
Ymin: -10, Ymax: 10
O Xmin: -5, Xmax: 5
Ymin: -5, Ymax: 5
Xmin: 0. Xmax: 10
Ymin: 0, Ymax: 10
Xmin: -10, Xmax: 0
Ymin: -10. Ymax: 0
O

- 70

this is the answer for you hope it

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.
