What is the nth term for 1 3 6 10 15 21?
f(n) = (n² + n) / 2 f(1) = (1² + 1) / 2 = 1 f(2) = (2² + 2) / 2 = 3 f(3) = (3² + 3) / 2 = 6 f(4) = (4² + 4) / 2 = 10 f(5) = (5² + 5) / 2 = 15 f(6) = (6² + 6) / 2 = 21
If f x equals x-x plus2 what does f-3 equal?
-1
What does f you times 2 mean?
F u times 2 means f*** you times twice
What are the zeros of f of x plus 2?
I think you might mean f(x)+2? Or do you mean f(x+2)? Either way it depends on what f(x) is.
What is 3 over 6 and 1 over f?
3/6 + 1/f = 1/2 + 1/f = (f+2)/2f
What is F 2 cattle?
F 2 cattle is cattle whit f 2
What is the Taylor Series of f of x equals x squared minus x cubed centered at a equals 2?
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
What is the answer to F times x equals x squared minus 3?
Are you trying to solve for x? Fx = x2 - 3 x2 - Fx - 3 = 0 x2 - Fx = 3 x2 - Fx + (F/2)2 = 3 + (F/2)2 (x - F/2)2 = 3 + (F/2)2 x - F/2 = ±[ 3 + (F/2)2 ]1/2 x = F/2 ± [ 3 + (F/2)2 ]1/2
How do you evaluate f x equals 3x plus 2 at f 2?
if f(x) = 3x + 2 and you're looking for f(2), just plug in 2 for x: f(2) = 3(2) + 2 = 6 + 2 = 8.
What are the factors of f squared plus 2f?
f^2 + 2f = f (f + 2)
How do you simplify the expression f plus 4(f-2)?
f+4(f-2)
If f(x) 2x3 - 2x2 plus 50 find f(-2).?
To find f(-2), substitute -2 into the function f(x). So, f(-2) = 2(-2)^3 - 2(-2)^2 + 50. Simplifying this expression gives f(-2) = 2(-8) - 2(4) + 50 = -16 - 8 + 50 = 26.
If f of x equals x to the second power plus 3x minus 2 then what is f prime of x and f prime of 2?
f(x) = x2 + 3x - 2 then f'(x) = 2x + 3 and then then f'(2) = 2*2 + 3 = 4+3 = 7
F(x) 3x plus 2 What is f(5)?
F(x) = 3x + 2 f(5) = 3*5 + 2 = 17
F to the second power plus 4 equals 5 to the second power What is F?
^ 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)
What is the nth term for 1 3 6 10 15 21?
f(n) = (n² + n) / 2 f(1) = (1² + 1) / 2 = 1 f(2) = (2² + 2) / 2 = 3 f(3) = (3² + 3) / 2 = 6 f(4) = (4² + 4) / 2 = 10 f(5) = (5² + 5) / 2 = 15 f(6) = (6² + 6) / 2 = 21
If f x equals x-x plus2 what does f-3 equal?
-1
