Answer:


f(-3)=24

Explanation:

So we have the function:


f(x)=|4x-2|+10

To find f(-3), substitute -3 for x:


f(-3)=|4(-3)-2|+10

Multiply within the absolute value:


f(-3)=|-12-2|+10

Subtract:


f(-3)=|-14|+10

The absolute value of -14 is 14. Thus:


f(-3)=14+10

Add:


f(-3)=24

And we're done!
