What is the value of f(-2) if f(x) = - 3x2 + 4x - 1

pashok25 [27]

Given the function below:

$\large{f(x) = - 3 {x}^{2} + 4x - 1}$

To find f(-2), we substitute x = -2 in the equation. Since f(-2) means the value of f(x) at x = -2.

$\large{f( - 2) = - 3 {( - 2)}^{2} + 4( - 2) - 1}$

Replace x-term to -2 and evaluate.

$\large{f( - 2) = - 3(4) - 8 - 1} \\ \large{f( - 2) = - 12 - 8 - 1 \longrightarrow f( - 2) = - 21}$

Answer

f(-2) = -21

How do you do this? Thanks for your time and effort!

V125BC [204]

Well first you have to simplify the denominators with x, by multiplying the denominator on the left times the top and bottom of the middle, and vice versa to get 10x/(4x^2-4x)-9(2x-2)/(4x^2-4x)=-1/4 and then you combine the fractions on the left to get 2(9-4x)/(4x^2-4x)=-1/4 and then you cross multiply the fractions to get 8(9-4x)=-4x^2+4x and then simplify to get 72-32x=-4x^2+4x and then 4x^2-36x+72=0 which then we can turn into 4(x-6)(x-3)=0 so x is 6 and 3

Terri is starting a babysitting service to make some extra money. She plans to charge a base fee of $10 plus $7 per hour. Write

antoniya [11.8K]

Given:

Terri plans to charge a base fee of $10 plus $7 per hour for babysitting.

To find:

The function that could be used to represent her total charge for the babysitting service, y, as a function of the number of hours she babysits, x.

Solution:

Let y be the total charge for the babysitting service for x hours.

Base fee = $10

Additional fee for one hour = $7

Additional fee for x hour = $7x

Total fee = Base fee + Additional fee for x hours

$y=10+7x$

Therefore, the equation of required function is $y=10+7x$ .
