Given the function rule f(x)=x^2-4x+3, what is the output of f(-3)?

Question

A- 24
B- 21
C- 0***
D- -3

Answer 1

No, it's not C.

f(-3) means substitute x = -3 to the function:
f(x) = x^2 - 4x + 3
f(-3) = (-3)^2 - 4(-3) + 3
f(-3) = 9 + 12 + 3
f(-3) = ?

Answer 2

So wouldn't it be 24? A?

Answer 3

that 9 should be negative right?

Answer 4

wait nevermind calculater being stupid

Answer 5

f(x) = x^2 - 4x + 3
f(-3) = (-3)^2 - 4(-3) + 3
f(-3) = 9 + 12 + 3
f(-3) = 21 + 3
f(-3) = 24
If you wanted to you could divide 24 by -3 to find f because f times -3 is 24. So...
24 / -3 = -8
f = -8?
I have no clue

Answer 6

The answer is A 24

Answer 7

ty @? and @Slushie

Answer 8

Given the function rule f(x) = x² – 4x + 3, what is the output of f(–2)?

Answer 9

To find out the output of f(-2), we need to substitute -2 for x in the equation f(x) = x² – 4x + 3 and simplify.

f(-2) = (-2)² – 4(-2) + 3

f(-2) = 4 + 8 + 3

f(-2) = 15

Therefore, the output of f(-2) is 15.

Answer 10

Given the function rule f(x) = x² – 4x + 3, what is the output of f(–3)

Answer 11

To find the output of f(-3), we need to substitute -3 for x in the equation f(x) = x² – 4x + 3 and simplify.

f(-3) = (-3)² – 4(-3) + 3

f(-3) = 9 + 12 + 3

f(-3) = 24

Therefore, the output of f(-3) is 24.
