These can be a bit tricky.  The teeny 1 there tells us this grid is 1x1 cells.   The open circles at the end of the segments indicate the endpoint is not part of the function.  The filled circles indicate that endpoint is part of the function.

The origin is where the x and y axes meet. f(-3) means we start at the origin and count three units to the left, left being the negative direction.  Then we eyeball the figure to see where the vertical line x=-3 intersects f.  It's at the black dot in the lower left quadrant, which is four down from the y axis, so the point (-3, -4)

That means f(-3)=-4

Answer: first choice

The perimeter of a rectangle is 62 m. The length is four more than two times the width. What is the length?
Travka [436]
--------------------------------------------------
Define length and width
--------------------------------------------------
Let x be the width
width = x
Length = 2x + 4

--------------------------------------------------
Formula
--------------------------------------------------
Perimeter = 2(length + width)

--------------------------------------------------
Find Length and width
--------------------------------------------------
62 = 2(2x + 4 + x)
62 = 2(3x + 4)            <em> ← combine like terms  </em> 
62 = 6x + 8                 <em>← remove bracket </em>  
62 - 8 = 6x                  <em>← minus 8 on both sides </em>
6x = 54                      <em> ← swap sides  </em>
x = 54 ÷ 6                   <em>← divide by 6 on both sides</em>
<em>x = 9 m</em>

--------------------------------------------------
Find Length and Width
--------------------------------------------------
Width = x = 9 m
Length = 2x + 4 = 2(9) + 4 = 22 m

--------------------------------------------------
Answer: Length = 22m
--------------------------------------------------
