What polynomial has a graph that passes through the given points?
Evgen [1.6K]
The answer is <span>B. y = x^3 + 4x^2 + 2x - 2 

A line that passes through all given point is the correct choice. Now, substitute x and y in all of the choices:

</span>B. y = x³ + 4x²<span> + 2x - 2 
Point 1: </span><span>(-2, 2) 
x = -2
y = 2
____
2 = (-2)</span>³ + 4 *(-2)² + 2 * (-2) - 2
2 = -8 + 4 * 4 + (-4) - 2
2 = -8 + 16 - 4 - 2
2 = 2
_____

Point 2: (-1, -1) 
x = -1
y = -1
____
-1 = (-1)³ + 4 *(-1)² + 2 * (-1) - 2
-1 = -1 + 4 * 1 + (-2) - 2
-1 = -1 + 4 - 2 - 2 
-1 = -1
____

Point 3: (1, 5) 
x = 1
y = 5
____
5 = (1)³ + 4 *(1)² + 2 * 1 - 2
5 = 1 + 4 * 1 + 2 - 2
5 = 1 + 4 + 2 - 2
5 = 5
____

Point 4: (3, 67) 
x = 3
y = 67
____
67 = (3)³ + 4 *(3)² + 2 * (3) - 2
67 = 27 + 4 * 9 + 6 - 2
67 = 27 + 36 + 6 - 2
67 = 67

So, line B passes through all choices.

The logarithmic expression ln(√e/y^3) can be rewritten as
kvv77 [185]

Answer:

\dfrac{1 - 6 \ln y}{2}

Step-by-step explanation:

\ln \dfrac{\sqrt{e}}{y^3} =

= \ln \dfrac{e^\frac{1}{2}}{y^3}

= \ln e^\frac{1}{2} - \ln y^3

= \dfrac{1}{2} \ln e - 3 \ln y

= \dfrac{1}{2} - 3 \ln y

= \dfrac{1 - 6 \ln y}{2}
