The function in vertex form is f(x) = (x-4)2-11
the y-intercept of the function is (0,5)
the function crosses the x-axis twice
That means he had 400 or 4000mm
What table represents g(x) = -2•f when f(x) = x + 4
g(x) = -2
<h3>;</h3>
f(x) = x + 4
f(-2) = -2 + 4
f(-2) = 2

Answer:
30.96 m²
Step-by-step explanation:
In white there are four parts of a circle, so we can split the 12 m in half to show the radius, and then solve to find the area of the full circle.
A = r²
a = (6)²
a = (36)
a = 113.04
Then you find the area of the whole box.
12 x 12 = 144
Then you subtract the area of the circle in white from the area of the whole box.
144 - 113.04 = 30.96 m²
So that’s the area of the shaded region.
