Divide the funny looking shape into many simple common figures and find the area of the common figures. Then add the areas of the figures to find the total area of the funny looking shape.
First, we'll want to write out the equation

then reduce what we can

so this means n can equal any whole number between 9 4/9 & 12, which gives us the options of {10,11}
Answer:
x = a/(a² + b²) or x = -1/a
Step-by-step explanation:
a(a²+ b²)x² + b²x - a =0
Use the quadratic equation formula:

1. Evaluate the discriminant D
D = b² - 4ac = b⁴ - 4a(a² + b²)(-a) = b⁴ + 4a⁴ + 4a²b² = (b² + 2a²)²
2. Solve for x


Answer:
a) g(x) = f(x) + 3
So g(x) is a vertical translation of f(x), 3 units upwards
b) g(x) = 3x² - 1 + 3
g(x) = 3x² + 2
The graph has shifted 3 units upwards, so has the vertex.
The vertex of f is (0,-1)
Whereas the vertex of g is (0,2)
-1 + 3 = 2
To solve this problem you must apply the proccedure shown below:
