Q2.Find the inverse y=(5x+2)/3 and evaluate y(-3)^-1.
Q3.State the domain and range of y=-x^2+2x-3.
Q4.Calculate the equation of the luine which passes through the point of intersection of x-2y-6=0 and 2x-y-5=0 and parallel to the line whose equation is x+4y-12=0.

Only doing 1 and 4

1:
2%28x%2B3%29%5E2-2%28x%2B3%29%2B3
2%28x%5E2%2B6x%2B9%29-2x-6%2B3
2x%5E2%2B12x%2B18-2x-3
highlight%282x%5E2%2B10x%2B15%29

4:
Finding the intersection
system%28x-2y=6%2C4x-2y=10%29
E2-E1:
3x=4
x=4%2F3
-
system%282x-4y=12%2C2x-y=5%29
E1-E2
-3y=7
y=-7%2F3

Parallel to x%2B4y=12 contain point ( 4/3, -7/3 ):
x%2B4y=4%2F3-7%2F3
highlight%28x%2B4y=-1%29
