Consider a family \(M\)
of quadratic functions, as shown in the picture. Any quadratic function in this family
is given by the analytic expression
\[
y = ax^{2} + bx + c
\]
where \(a\),
\(b\) and
\(c\) are real constants and
\(a\not = 0\). For each function
the set \(K\) denotes the
set of \(x\)-intercepts. Complete the statement. „The analytic expressions for functions in the family
\(M\) share
only ....”
the value of the coefficient \(b\)
the value of the coefficient \(a\)
the value of the coefficient \(c\)
the solution set \(K\)
