Evaluate the function at the indicated values. (If an answer is undefined, enter UNDEFINED.) f(x) = x2 + 7x
f(0) = 0
Correct: Your answer is correct.
f(3) = 30
Correct: Your answer is correct.
f(−3) = −12
Correct: Your answer is correct.
f(a) = a
Incorrect: Your answer is incorrect.
f(−x) =
f

1
a

=

just put the values of x in function

ex. (i) 0×2+7×0

the result would be zero

apply the same procedure in all

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

it shoild be o
