Find the range for the given domain: (-2,-1, and 0} and the function is y = 3x2

Range = {12, 3, 0}

Explanation:

This question isn't history; it's mathematics.

However, the solution is as follows:

Given

f (x) = 3x²

Domain = {-2, - 1, 0}

Required

Calculate the Range

To calculate the range, we simply plug in the values of the domain in the given function

Let the domain be represented by x; such that

x = {-2, - 1, 0}

When x = - 2

f (x) = 3x²

f (-2) = 3 * (-2) ²

f (-2) = 3 * 4

f (-2) = 12

When x = - 1

f (x) = 3x²

f (-1) = 3 * (-1) ²

f (-1) = 3 * 1

f (-1) = 3

When x = 0

f (x) = 3x²

f (0) = 3 * 0²

f (0) = 3 * 0

f (0) = 0

The range are the values of f (-2), f (-1) and f (0)

Hence, Range = {12, 3, 0}
