The y intercept is -2. There is two x- intercepts because it is a parabola so,
x=-1
x=2
The axis of symmetry is where it splits evenly so, we can conclude it is less than 1 and bigger than 0. I hope this makes sense.
It would be <span>1.42857142857.
To find the answer, you would do 6 divided by 4.2</span>
Using SOH CAH TOA
Sin =opposite/hypotenuse
that means opposite=2
Hypotenuse=3
Cos=Adjacent/Hypotenuse
Using Pythagorean theorem
Hyp^2=Opp^2 +Adj^2
3^2 =2^2+adj^2
9=4+adj^2
9-4=adj^2
5=adj^2
Taking the square root of both sides
√5=adj
:: cos=√5/3
1 and a fourth because 3 3/4 devided by three equals 1 1/4
