(3x2 + 4x - 2) - (5x + 7)

=3x2−x−9

Step-by-step explanation:

Let's simplify step-by-step.

=3x^2+4x−2−(5x+7)

=3x^2+4x+−2+−1(5x)+(−1)(7)

=3x^2+4x+−2+−5x+−7

Combine Like Terms:

=3x^2+4x+−2+−5x+−7

=(3x^2)+(4x+−5x)+(−2+−7)

=3x^2+−x+−9

=3x^2−x−9

the answer is 24

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
