1) not function because 6 number repeat in domain
2) Function
For 3 and 4 I guess it's
3) Function
4)not function
If any number repeat twice in the domain that will be not a function
Answer:
A. y = 1/2 x.
Step-by-step explanation:
Use the point-slope form of a linear (straight line) function:
y - y1 = m(x - x1)
m = 1/2, x1 = 4 and y1 = 2, so:
y - 2 = 1/2(x - 4)
y = 1/2x - 2 + 2
y = 1/2 x (answer)
Answer:
y= -2x+23
Step-by-step explanation:
Subtract 2x over
The Vertex of f(x)=|5x|+2 is (0,2)
and vertex of f(x)=|5x|-2 is (0,-2)
