Answer 1

The zeros of the function f(x) = x² − 10x + 21 are 3 and 7.

Step-by-step explanation:

The zeros of a function are the values of x for which the function equals zero. To find the zeros of the function f(x) = x² − 10x + 21, we set the function equal to zero and solve for x.

Start by factoring the quadratic expression: x² − 10x + 21 = (x - 3)(x - 7). Therefore, the zeros of the function are x = 3 and x = 7.

So, the correct answers are: 3, 7.
