Question

F(x) = 3x - 5x + 40: f(2).

Answer 1

Answer:

f(2) = 36

Step-by-step explanation:

Hello!

To find f(x), plug in 2 for x in the original equation.

Solve:

• f(x) = 3x - 5x + 40
• f(2) = 3(2) - 5(2) + 40
• f(2) = 6 - 10 + 40
• f(2) = -4 + 40
• f(2) = 36

The final solution is 36.

Answer 2

Answer:

Y = 36   or  F = -x+20

^ ^ ^ Not sure about what ur asking, so I put in 2 versions that I know of.

Step-by-step explanation:

Write out the equation:

f(2) = 3x - 5x + 40

If X is 2, then write the equation out as:

Y = 3(2) - 5(2) + 40

Now multiply:

Y = 6 - 10 + 40

Simplify:

Y = 36

_____

Let's solve for f.

f(2)=3x−5x+40

Divide both sides by 2.

2f/2 = −2x+40/2

f=−x+20

Answer:

f=−x+20
