If f(x)=2x+1 and g(x)=x^2-7, fing (f-g)(x)

(f-g)(x) = -x^2 + 2x + 8

Step-by-step explanation:

(f-g)(x) = 2x + 1 - (x^2 -7)

(f-g)(x) = 2x + 1 - x^2 +7

(f-g)(x) = -x^2 + 2x + 8

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
