Option 1To find the y-intercept of a quadratic that is in factor formed follow the steps below:
First take the factor form and put it into standard quadratic form
Standard quadratic form:
To put the the factor form of a qudratic into standard form, we use the foil method
(x-6)(x-2) =

Now to find the y-intercept, input 0 where the x is located:



y-intercept = (0,12)
Why did I use 0? Remember the y-intercept is where the line crosses the y axis so this means the x value of the y intercept is always = 0. Also, not, to find the y-intercept, you could of just multiplied the 6 and 2 in the factored form to get the 12 and since you know that the x is always 0 at the y-intercept, you know that the y-intercept is at (0,12)
Option 2Input 0 for x in f(x) = (x-6)(x-2)
f(x) = (x-6)(x-2)
f(0) = (0 - 6)(0 - 2)
f(0) = (6)(2) = 12
x = 0
f(0) = y = 12
y-intercept = (0,12)
Answer: 20 children
Step-by-step explanation:
<u>Given</u>
Year 4: 11 cannot swim
Year 5: 21 can swim
Year 6: 18 of 30 can swim
Total 96 children
Total 37 cannot swim
<u>First Step: find the number of people from year 5 who cannot swim</u>
- There are 30-18=12 people who cannot swim in year 6
- There are 11 who cannot swim in year 4
- Thus, we use the total number [37]-[year 4+year 6]=37-23=14 people who cannot swim in the year 5
<u>Second Step: find the number of children in year 5</u>
- There are 21 children who can swim
- There are 14 children who cannot swim
- 21+14=35 children
<u>Third Step: find the number of children in year 4 who can swim</u>
- There are 30 children in year 6
- There are 35 children in year 5
- There are 11 children in year 4 who cannot swim
- There are in total 96 children
- 96-30-35-11=20 children in year 4 who can swim
