Question

If f(x) = int(4x), find f(-1.8).

Answer 1

Answer: \(f(-1.8) = -2\)

Explanation:

To find the value of \(f(-1.8)\) when \(f(x) = \text{int}(4x)\), you need to evaluate the function at \(x = -1.8\). The function \(\text{int}(x)\) represents the greatest integer less than or equal to \(x\), also known as the floor function.

For \(x = -1.8\), the greatest integer less than or equal to \(-1.8\) is \(-2\).

So, \(f(-1.8) = -2\).
