Given the function f(x) = 7x2 - 2x + 8. Calculate the following values: f ( - 2) = f(-1) = f(0) = f(1) = f (2) =For the function + = 6x + 10, evaluate and fully simplify each of the following. f (x + h) = f( + h) - f(x) hUse the following functions to: find, simplify, and identify the domain of each of the function combinations. f(x) = 12 - 10x and g(x) = x+9 (a) (f + g) (ac) = Domain of (f + g) (x) : (b) (f - g) (2) = Domain of (f - g) (a) : (c) (fg) (z) = Domain of (fg) (x) : (d) Domain ofThe polynomial of degree 4, P (x ), has a root of multiplicity 2 at x = 1 and roots of multiplicity 1 at x = 0 and x = -1. It goes through the point (5, 144) Find a formula for P(a)
