Write the equation in vertex form

y=3x^2 +8x+2

y= -2x^2+6x-2

Part 1)

Part 2)

Step-by-step explanation:

Part 1) we have

Factor the leading coefficient 3

Complete the square

Rewrite as perfect squares

simplify

The vertex is the point

Part 2) we have

Factor the leading coefficient -2

Complete the square

Rewrite as perfect squares

The vertex is the point

step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
