Answer:
If you input a value of x then we get the output f(x) = y, which is the function of x. This is a function of x. Hence, x² = y is a function of x.
The last option seems the best one: the figure is composed of a square/rectangle and a triangle. The area of the rectangle is the product of its dimension (i.e.
), while the area of the triangle is half the product of the base and height (
).
The sum of the two areas is the area of the composite shape.
Answer:
5(w - 2)(w + 2)
Step-by-step explanation:
5w² - 20
5(w² - 4)
5(w - 2)(w + 2)
