SOLUTION: Assume f(x) = x^2 + 4 find the functional value (f-6) f(-6) = -6^2 + 4 f(-6) = 36 + 4 f(-6) = 40 I keep getting -36 for -6^2 or f(-6) = -32

Question 670138: Assume f(x) = x^2 + 4 find the functional value (f-6)
f(-6) = -6^2 + 4
f(-6) = 36 + 4
f(-6) = 40
I keep getting -36 for -6^2
or f(-6) = -32

Hi,

f(x) = x^2 + 4  

f(-6) = x^2 + 4 = (-6)^2 + 4 = 36+4 = 40    ||Note: (-6)(-6) = 36
