A Function is given f(x) = 4x - 8

what is the input of the function when the output is 20

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

false

inverse variation is not exponential

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
