For this case we have the following function:

f (x) = x ^ 4 + 2x ^ 2-1

What we must do is evaluate the value of x = 3 in the given function.

We have then:

f (3) = (3) ^ 4 + 2 (3) ^ 2-1

Then, Rewriting the function we have:

f (3) = (3) ^ 4 + 2 (3) ^ 2-1

f (3) = 81 + 18-1

f (3) = 98

Answer:

The value of the function evaluated for x = 3 is given by:

f (3) = 98

Answer:

k=10

Step-by-step explanation:

g(x)=2x^2+ kx+18

when x=-2

g(-2)=2 (-2)^2 -2k +18

Since when x is -2, y =6

6=2 (-2)^2 -2k +18

6=18+8-2k

2k=26-6

2k=20
