Match the function with the graph.

Option a.

Step-by-step explanation:

It should be noted in the attached graph that the vertex of the function is in point (6.0). and it is reflected in the y axis.

Therefore you should look for a quadratic function of the form The option that matches is option a.

You can test this answer by replacing values in the function and seeing that it matches the graph.

For example, observe in the graph that the point (4, -4) belongs to the function. Then when replacing f(4) in the function you must obtain f(4) = -4

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.
