Answer:

8

Step-by-step explanation:

f(- 2) =  8

f(-2) = 2 (-2) ^ 4 - 4 (- 2) ^ 3 - 11 (- 2) ^ 2 + 3*(- 2) - 6 = 2 * 16 + 32 - 44 - 6 - 6 = 8

Therefore the value of f(x) is 8 at x = - 2

Answer:

f(- 2) =  8

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = 2(-2)^{4} - 4(- 2)³ - 11(- 2)² +3(- 2) - 6

       = 2(16) - 4(- 8) - 11(4) - 6 - 6

      = 32 + 32 - 44 - 12

      = 64 - 56

      = 8

What's the value of x when f(x)=58
Natalka [10]
Infinite, because essentially the graph is going to have a horizontal line because f(x)=58/y=58 just means that the y will remain on 58 but the x can have whatever value.
