What are the domain and range of the function? a b c d what are the inputs of the function below? a b c d

Step-by-step explanation:

First, we know that log(0) goes to minus infinite, so the domain will be such than we never have a zero inside the logaritm, and we have:

Log (5 - x) this means that x can not be bigger than 5, then the correct option is the first one, x < 5

In the second problem we have a table of x and f(x) where the input values are the x, and the output values are the ones of f(x), (the values of x are the ones upside) -8, 2, 4 and 6, so the correct option here is the third option

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.
