WebWe end up looking for integer solutions of the above equation. Note that 5 divides all the coefficients except the one for a 3. So 5 must divide a, say a = 5 a 1. Substitute. Divide through by 5. We find that 5 now divides all the coefficients except the one for b 3. So 5 divides b, say b = 5 b 1. Substitute, divide by 5. WebApr 18, 2024 · Here we have the cube root function: g(x) = ∛(x - 5) This is a cube root, and it is negative when the argument is negative. So the function will be negative for the values of x such that: x - 5 < 0. x < 5. So, we can say that on the interval: (-∞, 5) the function g(x) is negative. Then the correct option is b.
