Question 4 Given the vertex and point, find the third point and determine the correct
equation for the quadratic.
Vertex (1, 1), Point (3,-7)
Oy=2(x - 1)? - 1
Of(x) = -2(x - 1)² + 1
Oy=2r2 + 4z - 1
O f() = -212 + 43 - 1

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
