Which of the following is a zero for the function f(x) = (x + 3)(x - 7)(x + 5)?
x = -7, x = -3, x = 3, x = 5
Solution:
Given: Function f(x) = (x + 3)(x - 7)(x + 5)
To find the number of zeroes in the given function, we check for f(x) = 0.
Hence, (x + 3)(x - 7)(x + 5) = 0
Here,
x + 3 = 0 or x = -3
x - 7 = 0 or x = 7
x + 5 = 0 or or x = -5
Therefore, the zero for the function is x = -3, x = 7 and x = -5.
From the given options, the zero for the function is x = -3.
Which of the following is a zero for the function f(x) = (x + 3)(x - 7)(x + 5)?
x = -7, x = -3, x = 3, x = 5
Summary:
The zero for the function f(x) = (x + 3)(x - 7)(x + 5) is x = -3.
