Answer:
x=sqrt(y+2), -sqrt(y+2)
Step-by-step explanation:
y=x^2-2
x^2=y+2
x=sqrt(y+2), -sqrt(y+2)
Answer:
The area is 64squared units
Step-by-step explanation:
Given
Required
The area of the polygon
First, we plot the given coordinates on a plane (See attachment)
From the attachment, we can see that the 4 coordinates make up a square.
Where
So, the area is:
Substitute for
<em>Hence, the area is 64 squared units</em>
3/8 because the total possible spots are 8 and 2,3,4 make up 3 of the 8 possible spots
Answer:
Second choice
Step-by-step explanation:
To find inverses, we follow the steps:
1. exchange variables x and y
2. solve for y in terms of x.
The resulting function is the inverse.
Take case 2 as an example:
f(x) = y = 2x-3
1. exchange x and y : x=2y-3
2. solve for y: x+3=2y => y=(x+3)/2 = g(x)
Since the inverse of f(x) is g(x)=(x+3)/2, the second choice is the answer.
