Given the quadratic function f(x)=3(x−1)(x−5) , what are the zeroes of the function?
Answer
A
3 and 5
B
1 and negative 5
C
negative 1 and negative 5
D
1 and 5
Explanation
To find the zeroes, set f(x) = 0: 3(x − 1)(x − 5) = 0. Since 3 is not zero, either x − 1 = 0 or x − 5 = 0, giving x = 1 and x = 5. The correct choice is 1 and 5.
