Evaluate the function f(x) = -2x + 7 at the indicated values. a) Find f(3). b) Find f(-7). a) f(3) = (Simplify your answer.) For y = f(x) = 7x³, find Ax, Ay, and Ax= Ay Ax' given x₁ = 1 and x2 = 6. For y = f(x) = 7x3, find Δx, Δy, and Δx= Ду ΔΧ given X1 = 2 and x2 = 6. Find dy. y=34+11x-5x³ dy = (Simplify your answer.) Find dy. y=x² (8-3) 6- dy = (Simplify your answer.)
