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}
