Answer:
all real numbers greater than or equal to -1
Step-by-step explanation:
In order to solve this problem we need to know the vertex and the direction its pointing.
First we expand,
x^2-6x+8
To find the x value of the vertex we use this formula (-b/2a).
-(-6)/2(1) = 3
Now we plug 3 in the equation to get the y value,
(3)^2 - 6(3) + 8 = 9 - 18 + 8 = -1
The vertex is (3,-1)
We know the graph points up because x^2 is positive
The vertex is the lowest point, so we now know that -1 is the starting range and if the graph is pointing up, that means all values greater than -1.
This leads to our answer all real numbers greater than or equal to -1.
Answer:
Step-by-step explanation:
Find the slope using the points, (1, -3) and (3, 1):
m = 2
Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in 
Subtract 2 from both sides
Plug in the value of m and b into the slope-intercept form equation, .
Thus:
