Determine which graphs are NOT functions.  Choose all that apply.

• 
• 
• 
• 

Given the relation shown, find the RANGE.

• {-5, -3, 0, 1, 2}

• {1, 6, -1, -5, 2}

• {-1, 0, 1, 4}

Given the relation shown, is it a function?

• Yes, it is a function.

• No, it is not a function.

Solve the equation

 $\frac{x-4}{5}=8$  

Which equation is equivalent to the one shown?

• none of these

• $75x+15=340$

• $42x+3=340$

• $65x+15=340$

Determine the appropriate values for the function

 $f\left(x\right)=x+1$  to complete the table shown.

• -3, -2, 0

• -4, -3, -1

• -2, -1, 1

• 3, 2, 0

Solve the equation

 $2\left(x+1\right)=2x+3$  

• x = 1

• x = -2

• infinitely many solutions

• no solutions

Solve the equation for y.

 $4x\ +\ 2y\ =\ 8$  

• y = 2x - 4

• y = -2x + 4

• y = -2x - 4

• y = -1/2 x + 2

Solve the formula for d:

 $C\ =\ \pi d$  

•  $d=\frac{\pi}{C}$  

•  $d=\pi-C$  

•  $d=\frac{C}{\pi}$  

•  $d=C+\pi$
