Question

If f(x) = -x² - 4x + 3, find f(4)

Answer 1

Plug in 4 for x.

Answer 2

you have -(x)^2-4(x)+3
put 4 where you see an x

Answer 3

note:-(x)^2 does not equal (-x)^2 and you have the fist one, so that term
-(x)^2 when x =4 is -(4)^2 = -16

Answer 4

4x^3-17x^2-42x/x^2y-13xy+42y

Answer 5

???

Answer 6

thats what im sayin lol

Answer 7

what you wann to do with ?

Answer 8

simplify

Answer 9

have you idea for ?

Answer 10

\[\large f(x) = -x^{2} - 4x + 3\]Then \[\large f(4) = -(4)^{2} - 4(4) + 3\]\[\large f(4) =?\]

Answer 11

4x^3-17x^2-42x
---------------- = ?
x^2y-13xy+42y

Answer 12

it doesnt give an =
