g(x) = 4

Step-by-step explanation:

If g(x) = √2x, then g(8) would be:

g(8) = √2(8)

Recall that g(x) is similar to a fancy way of calling "y" a different name so you know what you're talking about. If there were two equations, y1 and y2, wouldn't it be a lot easier if you just called them f(x) and g(x)? This way, you also know about the x.

Also, g(x) is pronounced "g of x."

So:

g(8) = √2(8)

       = √16

       = 4

So g(8) = 4.
