Answer

The function is one-to-one.

Steps

Step 1 :Use the definition of a one-to-one function to determine if the function is one-to-one.

Step 2 :To determine if a function is one-to-one, we need to check if every output value corresponds to exactly one input value.

Step 3 :For any two different input values, the output values must also be different.

Step 4 :For the given function q(x)=x317, we can use the fact that the cube function x3 is a one-to-one function.

Step 5 :Subtracting 17 from x3 does not change the one-to-one property of the function.

Step 6 :The function is one-to-one.
