What is the ordered pair of 5x plus 3y equals 58 5x-3y equals 22?
x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22
What is the area bounded by the graph of the function fx equals 1 - e to the power of -x over the interval -1 2?
What is the area bounded by the graph of the function f(x)=1-e^-x over the interval [-1, 2]?
Put x-3y equals -9 in function form?
y=1/3x+3
What is the average rate of change from x equals 2 to x equals 3 for the function f of x equals 3 ln x?
It is 1.2164
What is the rule for the function x equals 0 1 2 3 4 y equals 8 6 4 2 0?
y = 8 - 2*x
What is the ordered pair of 5x plus 3y equals 58 5x-3y equals 22?
x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22
What times what equals forty?
10x4 5x8 20x2 40x1 2x2x2x5
What is the solution for function of function of x equals function of x?
f(f(x)) = f(x). Only if f is 1-1 then we have a solution f(x)=x.
Does y equals x - 1 describe a function?
Yes.
Cos x equals -cos x plus 1?
No, but cos(-x) = cos(x), because the cosine function is an even function.
What is the formula for a rational function with x intercepts at x equals 3 and x equals negative 2. y intercept at y equals 12. a hole at x equals 1 and no horizontal asymptote?
f(x) = 2*(x-3)*(x+2)/(x-1) for x ≠1
If Sin equals x and Cos equals y then x squared equals what function of y?
If x = sin θ and y = cos θ then: sin² θ + cos² θ = 1 → x² + y² = 1 → x² = 1 - y²
Is y equals x2 plus 1 a function?
Yes. Think of y as being a function of x. y = f(x) = x2 + 1
What is the range of the function y equals -x 2 plus 1?
y < 1
Does the graph x-y2 equals 1 represent x as a function of y?
X - Y^2 = 1 - Y^2 = - X + 1 Y^2 = X - 1 Y = (+/-) sqrt(X - 1) now, X is represented as a function of Y. Function values are generally Y values.
What is the inverse function of f fx equals sqrt2x-1?
3
