Answer:
f(-2) is 14.
Step-by-step explanation:
We have been given the function:
\(f(x)=3x^2-x\)
We have to find f(-2)
That means put x= -2 in the given function we get:
\(3(-2)^2-(-2)\)
After simplification we will get:
\(12+2\)
After further simplification we will get the required result:
\(14\)
Hence, \(f(-2)\text{is}14\)
