Identify the vertex and the y-intercept of the graph of the function. y = –1.5(x + 2)^2

The vertex = (-2, 0)

The y-intercept of the equation is -6.

Step-by-step explanation:

Since, the vertex form of quadratic equation,

Where, (h,k) is the vertex of the equation,

Here, the given equation,

By comparing,

The vertex = (-2, 0)

Now, for y-intercept,

x = 0,

Hence, y-intercept of the equation is -6.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
