for a certain function f = f(x), we know that f is proportional to x and that the constant of proportionality is 20. find a formula for f.

a) f(x) = 20x

b) f(x) = 20

c) f(x) = x+20

f(x) = 20 x^20

If the table of the function contains exactly two potential turning points, one with an input value of –1, which statement best describes all possible values of m? m ≥ –12 –12 < m < 4 m ≤ 4 m ≥ 4 or m ≤ –12
