Answer:
A. 0
E. -3
F. 9
Step-by-step explanation:
You can't divide by 0; it is undefined. So if x cannot equal zero, then anything that turns the denominator to zero is an asymptote. Therefore, the roots of the cubic expression would be excluded, and we get our final answers.
Step-by-step explanation:
<u>Substitute x = -3, y = -3 into the </u><u>g</u><u>i</u><u>v</u><u>e</u><u>n</u><u> </u><u>equation:</u>
<u>Simplify and Solve:</u>
The point (-3, -3) doesn't satisfy the given equation.
(-1, 0)
As you can see, they're clearly intersecting at that point, which means that the solution is that point.
Answer:
f(x) = (x - 2)² + 2
Step-by-step explanation:
The vertex form of the quadratic function is:
f(x) = a(x - h)² + k
where:
(h, k) = vertex
The axis of symmetry is the imaginary vertical line where x = h
<em>a</em> = determines whether the graph opens up or down, and how wide or narrow the graph will be.
<em>h</em> = determines the horizontal translation of the parabola.
<em>k</em> = determines the vertical translation of the graph.
Given the vertex occurring at point (2, 2), along with one of the points on the graph, (4, 6):
Substitute these values into the vertex form of the quadratic function:
f(x) = a(x - h)² + k
6 = a(4 - 2)² + 2
6 = a(2)² + 2
6 = 4a + 2
Subtract 2 from both sides:
6 - 2 = 4a + 2 - 2
4 = 4a
Divide both sides by 4:
4/4 = 4a/4
1 = a
Therefore, the quadratic function in vertex form is: f(x) = (x - 2)² + 2
