absolute value graph looks like a V, with the vertex at the origin.
1. the domain (x-values) is: (∞, ∞) TRUE
2. the range (y-values) starts at the vertex: [0, ∞) FALSE
3. the function decreases when left of vertex and increases when right of vertex: decreases (-∞, 0) TRUE
4. f(x) = |x| = +/-x
f(-x) = |-x| = +/-x
f(x) = f(-x) so the function is even TRUE
5. every x-value has a corresponding y-value (there are no gaps) so the function is continuous. TRUE

The answer is A because the diagram shows
$12.50 is how much it would cost during the sale.
Cos A = adjacent/hypotenuse
Cos A = 9/26 = 0.346
<span>4x-2y=-1
</span><span>Slope = 2
x-intercept = -1/4
y-intercept = 1/2
</span><span>-4x+4y=-2
</span><span>Slope = 1
x-intercept = 1/2
y-intercept = 1/-2 </span>
