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
Hope I helped :)
x greater than negative 2, because ln(x) is undefined for x <= 0 (-2+2=0, -1.999...+2>0)
Answer:
Step-by-step explanation:
cos(y°) = 8/13
y° = arccos(8/13) ≅ 50°
Answer:
6 ft
Step-by-step explanation:
10ft + 2ft = 12ft
12ft - 6ft = 6ft
She flies an additional 2ft so you add to 10ft which becomes 12ft. She goes down 6ft so you subtract from 12ft and get 6ft.
