5 +1/4 f = 5 + f/4
^ means "to the power of" F ^ 2 + 4 = 5 ^ 2 F ^2 +4 = 25 F ^2+4 -4 = 25 -4 F^2 = 21 F = (square root of 21)
f+4(f-2)
If f(x) = 2 - 3x then f(4) = 2 - 3(4) so since 3 times 4 is 12, then f(4) = 2 - 12 which means f(4) = -10 Easy!
f(x)=x2-x3 f(2) = 4-8 = -4 f'(x) =2x-3x2 f'(2) = 4-12=-8 f''(x) = 2 -6x f''(2)= -10 f'''(x)= -6 f(n)(x) = 0 for all n > 3. f(x) = f(2) + (x-2) f'(2) / 1! + (x-2)2 f''(2) /2! + (x-2)3 f'''(2)/3! + . . . f(x) = -4 -8(x-2) -10(x-2)22/2-6(x-2)3/6 + 0 + 0 + ... f(x) = -4 -8(x-2) -5(x-2)2 - (x-2)3
