What is the range of the function y = -x ^2 + 1?

y ≤ -1
y ≥ -1
y ≤ 1
y ≥ 1

Step-by-step explanation:

Range is the set of y values for which the function is defined

To find out the range we look at the value of k in the vertex

General vertex form is :

where (h,k) is the vertex that is maximum when a is negative

From the given equation the value of k= -1

The graph reaches the maximum value at y=-1

So range is  

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

it's d
