• (-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)

• (-4, 0) and (4, 0)

• (-2, 0) and (4, 0)

• (0, 0) and (-4, 0)

• (0, 0) and (4, 0)

Answer explanation

To find the x-intercepts in Standard Form, you first have to factor out an x. Tha will leave you with x(x + 4). Any x on the outside will be (0, 0) and then you take the opposite of what is inside the ( ) or (-4, 0)

• left

• right

• upwards

• downwards

Answer explanation

If there is a negative sign immediately after the =, then it opens downwards. Otherwise it opens upwards.

• (-7, 5)

• (2, 5)

• (-5, 7)

• (-1, -36)

Answer explanation

Find the x-intercepts and then find the x value that is exactly in the middle. Substitute this x-value into the original equation to find the y-value.

• (0, -35)

• (7, -5)

• (5, 7)

• (0, 7)

Answer explanation

To find the y-intercept, multiply the two numbers in the equation. Remember to include any negative signs when you multiply.

• (0, 0) and (5, 0)

• (5, 0) and (-7, 0)

• (0, 0) and (-7, 0)

• (-5, 0) and (-7, 0)

Answer explanation

To find the x-intercepts, take the opposite values of the numbers in the ( ).

• upwards

• downwards

Answer explanation

If there is a - sign immediately after the = sign, then it opens downwards, otherwise it opens upwards.

• (-5, 2)

• (-2, -5)

• (5, 2)

• (2, 5)

Answer explanation

Take the opposite of the number inside the ( ) and then take the outside number (include the - sign if there is one).
