Step-by-step explanation:
To find the y-coordinate points we need to evaluate the function for all the [tex]x[/tex] values in the table. In other words, we need to replace [tex]x[/tex] with each value in our given function and simplify.
- For x = 0
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(0)=(0-2)^2-5[/tex]
[tex]f(0)=(-2)^2-5[/tex]
[tex]f(0)=4-5[/tex]
[tex]f(x)=-1[/tex]
Since [tex]x=0[/tex] and [tex]y=-1[/tex], our first point is (0, -1)
- For x = 1
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(1)=(1-2)^2-5[/tex]
[tex]f(1)=(-1)^2-5[/tex]
[tex]f(1)=1-5[/tex]
[tex]f(x)=-4[/tex]
Our second point is (1, -4)
- For x = 2
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(2)=(2-2)^2-5[/tex]
[tex]f(2)=(0)^2-5[/tex]
[tex]f(x)=-5[/tex]
Our third point is (2, -5)
- For x = 3
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(3)=(3-2)^2-5[/tex]
[tex]f(3)=(1)^2-5[/tex]
[tex]f(3)=1-5[/tex]
[tex]f(x)=-4[/tex]
Our fourth point is (3, -4)
- For x = 4
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(4)=(4-2)^2-5[/tex]
[tex]f(4)=(2)^2-5[/tex]
[tex]f(4)=4-5[/tex]
[tex]f(x)=-1[/tex]
Our fifth point is (4, -1)
Now we just need to plot each point in our coordinate plane and join them with the parabola as you can see in the attached picture.
