Work out 9/25 of 100
To do this divide 100 by 25 = 4
Then multiply 4 by the numerator : 9*4 = 36
This means 36 people didn't like the book
So if there's 100 students altogether and 36 didn't like the book,
100-36 = 64
64 people liked the book
First equal the equation to f(x) or y
f(x)= (x²+x-2)÷(x²-3x-4)
To find y-intercept, x coordinates have to be 0
f(0)=(0²+0-2)÷(0²-3(0)-4)
f(0)=-2/-4
f(0)=1/2 (y-intercept)
To find x-intercept, make y=0
0=(x²+x-2)÷(x²-3x-4)
0((x²-3x-4)=(x²+x-2)
0=x²+x-2
0=(x-1)(x+2)
x-1
x-1=0
x=1
x+2=0
x=-2
The x-intercepts would be 1, -2
