Have you learned slope yet? Pick two points from the graph and do x-y on the top and x-y on the bottom. That would give you your slope then you can graph it. For example (-2,-1) (-1,1)
-2-(-1)
-1-1
Then that would give you -1/-2 so technically -1/2<< this is what you graph
Table:
y = x²
can also be written as: f(x) = x²
Plug in each x value and calculate the output:
f(-4) = (-4)² = 16
f(-3) = (-3)² = 9
f(-2) = 4
f(-1) = 1
f(-
) = 
f(0) = 0
f(
) = 
f(1) = 1
f(2) = 4
f(3) = 9
f(4) = 16
Answers:
a) graph shown in picture
b) vertex is at (0, 0)
Yes because the thermometer reads temperatures higher than 2.12 degrees
On a coordinate plane it is negetive 5
We can see that
both lines intersects at origin
so, the solution is x=0 and y=0
now, we will check each options
option-A:


now, we can set them equal
and then we can solve for x



now, we can find y


so, solution is x=0 and y=0
so, this correct...........Answer
