Is this equation an identity? 100 - 7 = 90

No

Step-by-step explanation:

100-7 equals 93

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

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
