Question

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

Answer 1

Answer:

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}
