10x^2 - (2 - 3x) + (5x - 3x^2)
=7x^ + 2x - 2
(2y,1x) do u get it or am i not helping sorry if this doesnt help

Let's find the inverse of given function ~



[ now, replace f(x) and x with
]

That's the required inverse function ~
Answer:
The equation of straight line is 3 x-y-5=0
Step-by-step explanation:
The equation of straight line having slope m = 3 and passing through the point (2,1) is
the standard form of straight line is 
now substitute m = 3 and point (2,1) is




The equation of straight line is 3 x-y-5=0
