Identify the vertex and the y-intercept of the graph of the function. y = -1.5(x + 2)2
vertex, (0, -2); y-intercept, -2
vertex, (-2, 0); y-intercept, -6
vertex, (0, -2); y-intercept, -6
vertex, (-2, 0); y-intercept, -2

Step-by-step explanation:

vertex-form equation for a vertical parabola with vertex (h,k):

y = a(x-h)² + k

y = -1.5(x+2)²

vertex (-2,0)

y-intercept = -1.5(0+2)² = -6

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
