Q. f(x)=x(x−3)(x+4)(x+5)How many distinct zeroes does the function have?
Identify zeroes of the function: Identify the zeroes of the function by setting each factor equal to zero.x(x−3)(x+4)(x+5)=0The zeroes occur when x=0, x=3, x=−4, or x=−5.
Check for repeated zeroes: Check for any repeated zeroes. Each zero corresponds to a different factor in the function, so there are no repeated zeroes.
Count distinct zeroes: Count the number of distinct zeroes.There are 4 distinct factors that can be set to zero, so there are 4 distinct zeroes.
