Answer:
In the area formula, there are two dimensions that are multiplied, base and height. So, the units are also multiplied. Inches times inches is inches squared. Also, area is a measurement that counts how many squares fit inside of a shape, so it makes sense that the units are described as squared.
Step-by-step explanation:
F(x) = x² + 2x - 1
f(2) = 2² + 2 · 2 - 1 = 4 + 4 - 1 = 7
f(-2) = (-2)² + 2 · (-2) - 1 = 4 - 4 - 1 = -1
f(3) = 3² + 2 · 3 - 1 = 9 + 6 - 1 = 14
f(-3) = (-3)² + 2 · (-3) - 1 = 9 - 6 - 1 = 2
The range = {-1; 2; 7; 14}
