Question

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

Answer 1

y = cx^2 is a direct variation.

Explanation:

Hope it helps.

Answer 2

combined variation

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
