Question

Please really need help on these

Answer 1

2. True

3. Maximum

4.
`2(m-9)^2`

Explanation:

Question 2:

Yes, it is the vertex formula used to calculate the vertex of a quadratic funtion.

Question 3:

Since the first term of the equation has a negative coefficient, the parabola turns upside down, which opens down. Therefore the equation has a maximum.

Question 4:

`2m^2-36m+162\\`

Find the GCF:

`2(m^2-18m+81)`

Find the perfect square binomial:

`81*1=81\\\\(-9*-9)\\\\-9*-9=81\\\\-9-9=-18`

Therefore this equation can be written as a perfect square binomial.

`2(m-9)^2`
