Answer:
combined variation
Step-by-step explanation:
we have
[tex]y=cx^{2}[/tex]
we know that
a) in the interval ----> (0,∞)
If the value of x increase the value of y increase
so
Is a direct variation
b) in the interval ----> (-∞,0)
If the value of x increase the value of y decrease
so
Is a inverse variation
therefore
Is a combined variation
Answer:
y = cx^2 is a direct variation.
Step-by-step explanation:
