F(x) = -4x2 + 4x – 4<br> Find f(3)
ValentinkaMS [17]

F(3) occurs when x =3. So lets plug 3 into our equation.

f(3) = -4(3)^2 + 4(3)-4\\f(3) = -4(9) + 12- 4\\f(3) = -36 + 12- 4\\f(3)= -28

F(3) = -28

I hope this helps! :)

Irina18 [472]

Answer:

Her weekly allowance is $8.

Step-by-step explanation:

Let the weekly allowance of Ming is $x.

If she spends half of her weekly allowance playing mini-golf and to earn more money her parents let her wash the car for $5, then the remaining amount of money that she has = (\frac{x}{2} + 5) dollars.

Now, given that (\frac{x}{2} + 5) = 9

⇒ \frac{x}{2} = 4

⇒ x = $8

Therefore, her weekly allowance is $8. (Answer)
