Look at the following graph of the given equation. Determine whether the equation is a function. Explain why or why not.
y = 2 x + 2
On a coordinate plane, points are at (negative 1, 0), (0, 2), (1, 4), (2, 6).

Yes this is a function

Step-by-step explanation:

y = 2x + 2

0 = 2(-1) + 2

0 = -2 + 2

0 = 0

Yes

2 = 2(0) + 2

2 = 0 + 2

2 = 2

Yes

4 = 2(1) + 2

4 = 2 + 2

4 = 4

Yes

6 = 2(2) + 2

6 = 4 + 2

6 = 6

Yes

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:
