Answer:
See below ↓
Step-by-step explanation:
Missing values (a)
- [tex]\left[\begin{array}{ccc}-1&1\\?&?\end{array}\right][/tex]
- Substituting x = 1 and x = -1 respectively in the equation y = x² - 4x
- [tex]\left[\begin{array}{ccc}-1&1\\5&-3\end{array}\right][/tex]
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
