The graph of the function f(x) = 2x² - 3x - 2 has:
A maximum turning point.
A minimum turning point.
No turning point.
Both maximum and minimum turning points.
The expression x2 - (2x - 3)(2x + 3) when expanded and simplified gives:
3(3 - x²).
3(3 + x²).
(3 + x)(3 - x).
-3(3 + x²).
Given that (x − 2) is a factor of f(x) = x² - kx + 4,
the value of k is
4.
5.
-4.
0.
The remainder when x² - 2x + 7 is divided by (x + 4) is:
-17
15
-1
31
The number of factors in the expression (x + 1)(x + 2) is:
3.
