Need help with two questions please What is the domain of the function v=−6r2 if the range is v≤0?

For the function f(x)=x3, if the domain of x is R, what is the range of f(x)?

2/5

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

what’s the question?
