A linear function f(x) contains the coordinates (-9, 4) and (6,4). Joy says f(x) is a horizontal line, and Lu says f(x) is a vertical line. Which student correctly described the function? Explain. A. Joy because (-9,4) and (6,4) would have a slope of zero which is a horizontal line.

B. Joy because (-9,4) and (6,4) would have a slope of zero which is a vertical line.

C. Lu because (-9,4) and (6,4) would have a slope of zero which is a horizontal line.

D. Lu because (-9,4) and (6,4) would have a slope of zero which is a vertical line.

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

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.
