Answer:
The slope is 0
Step-by-step explanation:
This is a horizontal line, and all horizontal lines have a slope of 0.
(to see why, just pick any two points, and work out the change in x over the change in y. i.e. rise/run. Since the y coordinates are all equal to 2, the numerator will be 2 -2, meaning the fraction is 0).
Answer:
Option A
Step-by-step explanation:
The set of values for which y is a function of x is the set where each x-value has exactly on y-value. No x-value has more than 1 y-value.
✅Option A: y is A FUNCTION of x because it has exactly one y-value assigned to each x-value.
❌Option B: y is NOT a function of x because there are two y-values, 4 and 2, that are assigned to one x-value, -1.
❌Option C: y is NOT a function of x because there are two y-values, 10 and 12, that are assigned to one x-value, 1.
❌Option D: y is NOT a function of x because there are two y-values, 2 and 4, that are assigned to one x-value, -1.

We are comparing maxima. From the graph we know that the max of one graph is +2 at x = -2. What about the other graph? Need to find the vertex to find the max.
Complete the square of <span>h(x) = -x^2 + 4x - 2:
</span>h(x) = -x^2 + 4x - 2 = -(x^2 - 4x) -2
= -(x^2 - 4x + 4 - 4) - 2
=-(x^2 - 4x + 4) -2+4
= -(x-2)^2 + 2 The equation describing this parabola is y=-(x-2)^2 + 2, from which we know that the maximum value is 2, reached when x = 2.
The 2 graphs have the same max, one at x = -2 and one at x = + 2.
