Answer:
Those functions are for a graph.
Step-by-step explanation:
You can compare them by heading to a website like desmos and plugging in each function, I think they even do tables as well.
These are functions that can be graphed, I assume you know what that is, if not, look it up.
good luck
Answer:
y = 3x + 4
Step-by-step explanation:
y = mx + b
b = y-intercept so:
b = 4
Since 4 is the y-intercept that means (0, 4).
To find slope:
m=(y2-y1)/(x2-x1)
m=(4 - 10)/(0 - 2)
m= (-6)/(-2)
m= 3
Slope-intercept:
y - y1 = m(x - x1)
y - 10 = 3(x - 2)
y - 10 = 3x - 6
y = 3x + 4
Dan's age is x.
Jack is three years older than Dan, so his age is x+3.
Harold is twice as old as Jack, so his age is 2(x+3).
Harold's age is five times Dan's age.

Jack is 5 years old.
Answer:(x-3) (x+3)
