question 1)
D = {[x, f(x)]: (-1, 3), (0, 2), (1, 3), (2, 6), (3, 11)} Write the rule for f(x).
when x = 0 , f(x) = 2
f(x) = x^2 + 2 ....this is the rule
question 2)
Given: F(x) = 3x^2 + 1, G(x) = 2x - 3, H(x) = x
F(-2) = 3(-2)^2 + 1 = 12 + 1 = 13
F(-2) = 13
question 3)
Given: F(x) = 3x 2 + 1, G(x) = 2x - 3, H(x) = x
F(x) + G(x) = 3x^2 + 1 + 2x - 3
F(x) + G(x) = 3x^2 + 2x - 2
