Please help with this homework question!!! suppose f(x) = x (quadratic 2 or to the power 2)+8x-4. compute the following. a. f(-1) + f(1)    b. f(-1) - f(1) please note that the f means function. Solution f(1) = 1^2 +8-4 = 5 f(-1) = 1 -8-4 = -11 a) f(-1) +f(1) = -11+5 = -6 b) f(-1) -f(1) = -11-5 = -16 .

suppose f(x) = x (quadratic 2 or to the power 2)+8x-4. compute the following.
a. f(-1) + f(1)Â Â Â Â b. f(-1) - f(1)
please note that the f means function.
Solution
f(1) = 1^2 +8-4 = 5
f(-1) = 1 -8-4 = -11
a) f(-1) +f(1) = -11+5 = -6
b) f(-1) -f(1) = -11-5 = -16
