If fx equals 3x-5 then f2 equals?
fx=3x-5 f=(3x-5)/x f2=(6x-10)/x /=divide
What is the value of fx at x-2?
That depends what the function is! Just replace every occurrence of "x" by "x-2", and do any required simplifications.
What is the x intercept of fx equals x-5 squared?
y = f(x) = (x-5)2. At x = 5, the y value is zero, so the point (5,0).
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
If fx equals x2 then fx-1 equals?
