# Which are zeroes for the function f(x) = (x + 3)(x − 7)(x + 5)?

Polynomial functions are those function which consists of one or more variables with degree more than one. There are many types of polynomials like quadratic polynomial functions, cubic functions, etc.

## Answer: The zeroes of the function f(x) = (x + 3)(x − 7)(x + 5) are x = -3, x = 7 and x = -5.

Let's understand the solution in detail.

**Explanation:**

The zeroes are those values of the variable for which the polynomial as a whole has zero value.

To find the number of zeroes in the given function, we check for f(x) = 0.

Hence, (x + 3)(x − 7)(x + 5) = 0

Now, using the zero product rule of polynomial functions, we see that:

⇒ x - 3 = 0 or x = 3

⇒ x + 7 = 0 or x = -7

⇒ x + 5 = 0 or x = -5

Hence, we have three roots in this function. Therefore, it is a cubic function.
