Question

Find f(-3) for f(x) = -2x + 5.

A. -1

B. 10

C. -10

D. 11

Answer 1

`\boxed{ \sf{ \bold{ \boxed{11}}}}`

Option D is the correct option.

Explanation:

Given,

`\sf{f(x) = - 2x + 5}`

To find : f ( - 3 )

Let's find:

`\sf{f( - 3) = - 2 * ( - 3) + 5}`

Calculate the product

`\sf{ = 6 + 5}`

Add the numbers

`\sf{ = 11}`

Hope I helped!

Answer 2

Answer: f(-3) = 11

Step-by-step explanation: Here we're given the function

f(x) = -2x + 5 and we're asked to find f(-3).

In other words, if we put an x into our function, we get a -2x + 5 out.

So what happens when we put a -3 into the function?

Well if we put a -3 into the function,

that's f(-3), we get a -2(-3) + 5 out.

Now all we have to do is simplify on the right side,

-2(-3) is 6, so we have 6 + 5 which is 11.

So f(-3) is 11.
