Yes! Every input has ONE output
Is the following set of points a function? Explain why or why not.
Yes! Every input(x) has ONE output(y)
Is the following set of points a function? Explain why or why not.
NO! 3 has two outputs
Solve for y in this equation to determine if it is linear. 10x + 5y = 15
y = -2x + 3 , it IS LINEAR
Is this a linear function? Solve for y to determine -12x = 18 + 6y
Yes! -3 - 2x = y
Is this a linear function?
NO, it does not follow y = mx + b

-6 to +6 OR infinite
What is the Range of the function?
0 to 6 OR 0 to positive infinity
What is the Range of the function?
1 to -3
What is the Domain of the function?
-3 to 3
What is the y-intercept according to y = 2/3x ?
0
What is the equation for this graph?
