If f(x)=3x+10x and g(x)=5x-3, find (f-g)(x)

Sphinxa [80]

$f(x) = 13x\\g(x) = 5x - 3\\f(g(x)) = 13(5x-3)\\f(g(x)) = 65x - 39$

Answer:

$7$

Step-by-step explanation:

So we have the expression:

$|3x-1|$

And we want to evaluate it for x=-2.

So, substitute -2 for x:

$|3(-2)-1|$

Multiply:

$=|-6-1|$

Subtract:

$=|-7|$

The absolute value of a negative is positive. So:

$=7$

And we're done!
