Have you started by drawing the graphs?
(i) Use the graph to find approximate roots of the equation 1/x=2x+3 showing your method clearly.
(ii) Rearrange the equation 1/x=2x+3 to form a quadratic equation. Solve the resulting equation,leaving your answers in the form p+_sqrtq/r
(iii) Draw the graph y=1/x + 2,x ≠ 0 on the grid used for part (i).
(iv) Write down the values of x which satisfy the equation 1/x+2=2x+3
I havent a clue as to where to start than ks in advance
