• A function f (x) = x2 is given. Answer the following question for the function f(x).
(i) What is the algebraic nature of the function?
(ii) Write the name of the locus of the curve.
(iii) Write the vertex of the function.
(iv) Write any on property for sketching the curve.
(v) Write the domain of the function.​

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.
