<span>The correct answer is D) g(x) = -(x + 2)^2. The given formula F(x) = x^2 creates a parabola that is open at the top. To reflect this figure across the x-axis and have it open at the bottom, the y-position of the figure on the coordinate system for every x value, which is F(x) = y = x^2 has to be inverted. This is done by negating y and respectively x^2, so to reflect the figure on the x-axis the formula would now look like this: F(x) = -y = -x^2. To move any parabola two units to the left and thereby have its root be at -2, you would simply subtract -2 from every x-position of the figure in the coordinate system. For an inverted parabola like this one the value to move it on the x-axis has to be added instead and this results in the formula from answer D: g(x) = -(x+2)^2</span>
Based on the given situation above and given that the Cost is C and x is for the credit hours taken, and that per hour is $160 with an additional $50 to it, the equation would be like this: C(x) = 160x + 50. So the correct answer would be option C.
Answer:
first 2/21 2nd 4/43
Step-by-step explanation:
Given:
The quadratic function is

To find:
The number of zeros.
Solution:
We know that,
Number of zeros of a polynomial = Degree of the polynomial.
We have, a quadratic function is

Here, degree of function is 2.
For zeros
.


Therefore, the number of zeros of given quadratic function is 2 which are 0 and 0.
The sum of 3a²-a-3 and 2a-9 is 3a²+a-12
3a²+a-12 - (a²-3a-7) = 3a²+a-12 - a² + 3a + 7 =
2a² +4a - 5
