Answer:
Step-by-step explanation:
vertex form of quadratic: y = a ( x − h ) ^ 2 + k
h= -2 , k = -2
y=a(x+2)^2-2
Substitute (-1,1)
1=a(-1+2)^2-2
a=3
y=3(x+2)^2-2
Expanding and give
y=3x^2+12x+10
Answer:
find the classmark of each interval
- forexample
- (140+150)/2
- (150+160)/2
do the same up to (190+200)/2
then
draw a graph by using frequently (number of weeks) on y-axis against classmark on x-axis
Answer:
Relationship between temperature at different times of the day during the Winter period in places like Alaska and Minnesota in the USA.
Step-by-step explanation:
An example of a relationship that would have a negative number in the domain or range would be the relationship between the temperature at different times of the day during the snow period in the winter. It's well known that in places like Alaska and Minnesota in the USA, that during the winter when there's very heavy snow, the average temperature is usually below 0°C. The temperature is the dependent variable and is most likely negative in those 2 states and thus the range would have negative numbers.
