Find the unknow value in the proportion: 7/75=x/75-
a. 1.4
b. 161
c. 3
d. 35

Work is attached in the image below.

Use cross-products.

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
