Seven houses on a block have values of $105,000, $110,000, $110,000,
$117,000, $125,000, $135,000, and $138,000. When an eighth home is
built on the block, the average home value for the block is $122,750.
What is the value of the new home?

the square root of what number? if you add that, then someone will probably answer the question.

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
