Question

Identify the variation as direct, inverse, joint or combined. y = cx²

Answer 1

Y varies directly with x squared

Answer 2

Answer:

combined variation          

Step-by-step explanation:

we have

$y=cx^{2}$

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
