What does this graph look like? What is the function? Here are the clues. 1. It is a graph of a function. 2. It is continuous. 3. It is increasing for all values less than -2. 4. It is decreasing for all values from -2 up to 8. 5. It is increasing again for all values greater than 8. It has an x-intercept of 5 and a y-intercept of 2.

first one because it can't have a fraction in it

step-by-step explanation:

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.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
