Question

Find the range of f(x) = 3x}^{2}+ 1 when domain = {-3, 2, 4,0}.​

Answer 1

Domain

{

x

∈

R

}

Range

{

y

∈

R

}

Explanation:

This is just the equation of a straight line. The function is continuous so the domain is:

{

x

∈

R

}

The minimum value is

−

∞

The maximum value is

∞

So the range is:

{

y

∈

R

}
