Let’s substitute x values of the minimum point of the graph into each equation and see which equation gives the correct equation ;
x = -3
y = 2
1. y = (x+3)^2-2
= (-3+3) ^2 -2
= 0^2 -2
= -2
Therefore first equation is wrong
2. y = (x-3)^2 -2
= (-3-3)^2 -2
y = 36-2
y = 34
Since y isn’t 34 the second equation is wrong
3. y = (x+3)^2 +2
= (-3+3)^2 +2
= 0^2 +2
= 2
Since y =2 the third equation is correct
Therefore third equation is correct
Answer: yes is it a function
Step-by-step explanation:
A graph is a function when there is only one y value for each x value. You can also use the vertical line test. This example is a “quadratic function”.
Answer:7.5
Step-by-step explanation:add all sides and then divide by 4
Answer:
(0,5) (1,3) (2,1)
Step-by-step explanation:
Answer:
The required co-ordinate is (-2, -5).
Step-by-step explanation:
For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be:
.
Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:

= (-2, -5)
The reflected point is (-2, -5).
