The function f(-4) has a value of -158
How to evaluate the function?
From the question, we have the following function that can be used in our computation:
f(k) = 6k+ + 2k3-6,
Rewrite properly
So, we have
f(k) = 6k + 2k³ - 6,
The notation f(-4) means that k = -4
So, we have
f(-4) = 6(-4) + 2(-4)³ - 6,
Evaluate
f(-4) = -158
Hence, the value is -158
