For this case we have the following function:
[tex]f (x) = x ^ 4 + 2x ^ 2-1[/tex]
What we must do is evaluate the value of x = 3 in the given function.
We have then:
[tex]f (3) = (3) ^ 4 + 2 (3) ^ 2-1[/tex]
Then, Rewriting the function we have:
[tex]f (3) = (3) ^ 4 + 2 (3) ^ 2-1[/tex]
[tex]f (3) = 81 + 18-1[/tex]
[tex]f (3) = 98[/tex]
Answer:
The value of the function evaluated for x = 3 is given by:
[tex]f (3) = 98[/tex]
