i think im not sure if i am wrong tell me and i wiil redo! :)
Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result
x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7
x=4, y=28, 28=k(4), k=7
The constant of proportionality is 7; we check 2×7=14, 11×7=77
Answer: k=7, y=7x
The function f(x) takes on the value 2 when x = -7 and x = -3, and thus the corresponding points are (-7,2) and (-3,2).
The points where g(x) = 0 are called "roots" or "solutions," and is (3,0).
f(x) > g(x) on the approx. interval (-9, -3/4).
