So you have to substitute these values in to the equation and solve.
3(-2) +5(11-8)
-6+5(3)
-6+15
9
Answer:
Step-by-step explanation:
We don't need choices to find out the correct answer. Solve this problem by completing the square. Begin by setting the quadratic equal to 0 and moving over the constant, like this:
and factor out the -1 in front of the x-squared, since the leading coefficient HAS to be a 1:
Now take half the linear term, square it, and add it to both sides. Our linear term is -2. Half of -2 is -1, and squaring that gives us 1. So we add a 1 into both sides. But that -1 out front there on the left is a multiplier, so what we actually added in was -1(1) which is -1:

On the left side we have a perfect square binomial, which is why we do this, and on the right side we have -2:
and we can move that constant back over and set the quadratic back equal to y:
which gives us a max height of 2.
(If this was modeling parabolic motion, we would know that the time it takes to get to that max height is 1 second. The vertex of this parabola is (1, 2))

Answer:To find the x-intercept, substitute in 00 for yy and solve for xx. .
x-intercept(s): (1,0),(−4,0)(1,0),(-4,0)
y-intercept(s): (0,−4)
Step-by-step explanation:Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: (−3/2,−25/4)(-3/2,-25/4)
Focus: (−3/2,−6)(-3/2,-6)
Axis of Symmetry: x=−3/2 x=-32
Directrix: y=−13/2 y=40−3−4−32−254−1−60−4
