Can anyone help me? I just learned this and i dont understand
Will you please explain to me how to get the answer please?
thanks xx

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.

For a function f(x), a) if f(7) = 22 then f^-1(22) = b) f^-1(f(c)) =
