Solution

$y = 5 - 2 x$
$x$ $2$ $\frac{5}{2}$
$y$ $1$ $0$
$(x, y)$ $(2, 1)$ $(\frac{5}{2}, 0)$

y = p (x) = x^{3} - 2 x + 3

y = x^{2} - 2 x + 5

(1) Draw the graph of y = x² and y = 2x + 3 and hence solve the equation x² − 2x − 3 = 0.

(2) Draw the graph of y = 2x²and y = 3 − x and hence solve the equation 2x² + x − 3 = 0.

(3) Draw the graph of y = 2x² and y = 3 + x and hence solve the equation 2x² − x − 3 = 0.
