<h2>True </h2>
<h3>This curve passes the vertical line test, therefore it is a function.</h3>
<h3>The idea behind the vertical line test is that if you draw any vertical line, it has to intersect the curve only once. If there is more than 1 intersection, then it is not a function.</h3>
ps: This is a quadratic function of equation

Answer:
10+30r
Step-by-step explanation:
-2+5(2+6r)
expand 5(2+6r)
5x2=10
(6r)x(5)=30r
so it is 10+30r
then add that to -2
8+30r
Hope that helps :)
Answer:
(-2)^2-(-8)+1
Step-by-step explanation:
w^2-v+1
(-2)^2-(-8)+1
15.7 Gallons
Each wall is 15*30 = 450
450* 4 walls = 1,800
Area of triangles are 15*15/2 = 112.5
112.5 * 4 triangles = 450
1,800 + 450 = 2,250
2,250/143 = 15.73
