algebra 2 problem

Question

F(x) = 9x^4-2x^2+6x-1; [-2,0]

 

what is the value –f f(-2)?

Answer 1

Hey! Lets solve this shall we ?

So, we begin by declaring a function f(x) = 9x⁴ - 2x² + 6x -1 in the interval [-2, 0]. Then we set x = -2 such that

f(-2) = 9(-2)⁴ - 2(-2)² + 6(-2) - 1 = 123. Finally, we take the composition of itself f[f(-2)] such that

f[f(-2)] = f[123] = 9(123)⁴ - 2(123)² + 6(123) - 1 = ?

I hope this helped!
