Answer:
f(x) is 579.
Explanation:
The equation y=9x^6+x^4-2x^2-5 represents a function where y depends on the value of x. To find the f(x) of this function, we simply replace y with f(x), which gives us:
f(x) = 9x^6 + x^4 - 2x^2 - 5
This means that if you plug in a specific value of x, the function will output a corresponding value of f(x). For example, if you plug in x=2, you would get:
f(2) = 9(2)^6 + (2)^4 - 2(2)^2 - 5
f(2) = 9(64) + 16 - 8 - 5
f(2) = 576 + 3
f(2) = 579
So when x is 2, f(x) is 579.
