• Yes, since when you plug in the values for x, you get the left side and the right side of the equation to be equivalent, this means the equation is an identity.

• Yes, since when you distribute the x and the -1 on the left side of the equation you get equivalent expressions, this means the equation is an identity.

• No, since when you distribute the x and the -1 on the left side of the equation you get two equations that are not equivalent, there the equation is not an identity.

• What's an identity?

At what value of c does the graph has a vertical asymptote? Explain how you know what this asymptote means in this situation?

• 12, if the current is going the same speed as the boat, the boat will not move

• 12, it means if speed of boat is 12 the current doesn't matter

• 100, it means the boat is going too fast

• No vertical asymptote, division by zero is fun, all the cool kids are doing it

What equation in Factored Form represents this graph?

• v(x) = (x +2 )(x - 4)

• v(x) = (x - 1)(x + 9)

• v(x) = (x - 2)(x + 4)

• v(x) = (x - 0)(x - 1)

Answer explanation

Find the x-intercepts and put the opposite numbers in the equation.

CCSS.HSF-IF.C.8A

• (-4. 0)

• (0, 0)

• (4, 0)

• (-2, -4)

Answer explanation

Remember that to find the vertex in standard form, you need to find the x-intercepts and then find the x-value in the middle of the intercepts. Substitute the x-value into the original equation to find the y-value.

• (-4. 0)

• (0, 0)

• (4, 0)

• (-2, -4)

Answer explanation

In Standard Form, the y-intercept is the "c" value (the number that does not have a variable). So it would be (0, c)
