Missing values (a)

• $\left[\begin{array}{ccc}-1&1\\?&?\end{array}\right]$
• Substituting x = 1 and x = -1 respectively in the equation y = x² - 4x
• $\left[\begin{array}{ccc}-1&1\\5&-3\end{array}\right]$

Curve which matches the equation

• On solving y = x² - 4x = x(x - 4) ⇒ x = 0, 4
• It intersects the x axis at 0 and 4
• The blue curve is the right one
