Question

If f(x) = 2x – 10, what is f(4)

Answer 1

Hi! Hope you're enjoying your day!

In order to solve this, all we have to do is plug in the value of x.

So we're given that

f(x)=2x-10

So f of x is equal to 2 times x minus 10.

Thus

f of 4 is equal to 2 times 4 minus 10 (it can be simplified, right?) :)

f(4)=8-10

f(4)=-2

Hence, the answer is

`\boxed{\boxed{\bold{f(4)=-2}}}`

Hope everything is clear.

If you have any questions, please ask.

`\rule{200}{2}`

Answer 2

I got you :)

Explanation:

F(x)=2x-10

Ok, so when you need to know f(4) you plug in 4 for x

f(4)=2(4)-10

2x4 = 8

8-10= -2

f(4)= -2

Hope this helps!
