What is the zeroes of the function f(x) = x^2 + 3x - 10?

-2, -5
-2, 5
2, -5
2, 5

The correct answer is: 2, 5

The zeroes of a function are the values of x where the function equals zero. In this case, the function f(x) = x^2 + 3x - 10 has two zeroes, which are 2 and -5. This means that when x = 2 or x = -5, f(x) = 0. To determine the zeroes of a function, we can use the quadratic formula or factor the function. In this case, factoring is easier since the first term is just x^2. By factoring, we get (x + 5)(x - 2) = 0. Therefore, the zeroes are -5 and 2. Option A is incorrect because x = -2 does not produce a zero when substituted into the function. Option B is incorrect because x = 5 does not produce a zero when substituted into the
