<span>Given the quadratic equation: f(x) = -2x^2 - 2x - 1, the axis of symmetry can be obtained by finding the line that divides the function into two congruent or identical halves. Thus, it should pass through the vertex and is equal
to the x-coordinate of the vertex. </span>
<span>Note that a quadratic
equation in standard form: y = ax^2 + bx + c, has the vertex located at (h,k) where, h = -b/2a and k is determined by evaluating y at
h. In this case, a = -2, b = -2, thus, h = -0.5, k = 0.5. Thus, the vertex is located at (-0.5, 0.5) and the axis of symmetry is at x = -0.5. </span>
Step-by-step explanation:
Given: and
We can solve for f(x) by writing
Let
Then
We know that f(0) = 0 so we can find the value for k:
Therefore,
The first one would be 190 and the second one would be 107
Answer:
The answer is A
Step-by-step explanation:
Answer:
A. 13
Step-by-step explanation:
When you plug the numbers in, 4 times 13 = 52+9=61 and 63 is still greate so anything above 13 would make the sentence correct. So that is why 13 is NOT a solution.
