As per given by the question,
There are given that the function
[tex]f(x)=2x^3+x^2-3x-1[/tex]
Now,
For find the value of f(1),
Put x=1 into the given function
So,
[tex]\begin{gathered} f(x)=2x^3+x^2-3x-1 \\ f(1)=2(1)^3+(1)^2-3(1)-1 \\ f(1)=2+1-3-1 \\ f(1)=-1 \end{gathered}[/tex]
Hence, the value of f(1) is -1.
