1.05 is the answer to this question.
Answer:
Step-by-step explanation:
The first parabola has vertex (-1, 0) and y-intercept (0, 1).
We plug these values into the given vertex form equation of a parabola:
y - k = a(x - h)^2 becomes
y - 0 = a(x + 1)^2
Next, we subst. the coordinates of the y-intercept (0, 1) into the above, obtaining:
1 = a(0 + 1)^2, and from this we know that a = 1. Thus, the equation of the first parabola is
y = (x + 1)^2
Second parabola: We follow essentially the same approach. Identify the vertex and the two horizontal intercepts. They are:
vertex: (1, 4)
x-intercepts: (-1, 0) and (3, 0)
Subbing these values into y - k = a(x - h)^2, we obtain:
0 - 4 = a(3 - 1)^2, or
-4 = a(2)². This yields a = -1.
Then the desired equation of the parabola is
y - 4 = -(x - 1)^2
The production cost is an illustration of a quadratic function
<h3>How to determine the equation</h3>
We have the following parameters:
- Computing components (a)
- Number of devices (x),
- Labor (b)
- Savings on reusable material (c)
Using the instructions in the question, the equation of the production cost would be:
Hence, the production cost is
<h3>Change the subject of the equation</h3>
In (a), we have:
Subtract bx - c from both sides
Divide through by x^2
Hence, the equation that represents the computing component is
