Write a direct variation equation that relates the two variables. then solve.
6. suppose y varies directly as x, and y= 16 when x = 8. find y when x = 16.

What is the equation of the graph that represents f(x)=x^4 stretched vertically by 2 and shifted up 3 spaces

What are the domain and range of the function? f(x) = -4 (sqrt)x
