Answer:
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.
