5what is the range of y = -x2 - 2x + 3?
ax< 4
b x2-4
c y< 4
dy2-4

Step-by-step explanation:

we have

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex is a maximum

The vertex is the point (h,k)

The range of the function is the interval (-∞,k]

so

Convert the quadratic equation in vertex form

Factor -1 leading coefficient

Complete the square

Rewrite as perfect squares

The vertex is the point (-1,4)

therefore

The range is

use formula for the circle a=3.14

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
