Find the inverse of f x 3x plus 9?
f(x) = 3x + 9 y = 3x + 9 so 3x = y - 9 x = y/3 - 3 Therefore, the inverse function is g(x) = x/3 - 3
What is the inverse of 2x-8?
y = x² - 2x - 8 Swap x and y to find the inverse: x = y² - 2y - 8 Now get y by itself: y² - 2y = x + 8 (Complete the square): y² - 2y + 1 = x + 9 (y - 1)² = x + 9 y - 1 = ±√(x + 9) y = 1 ±√(x + 9) Then there are two functions: f(x) = 1 - √(x + 9) and f(x) = 1 + √(x + 9) but an inverse can only be one function. The functions above are a mirror image of the original function, but it is not an inverse (graph these functions). There is no inverse. Everything above is completely wrong. This is the inverse: (x+8)/2 I don't know where the x² came from in the first answer, but to work out the question as asked: if y=2x-8 y+8 = 2x (y+8)/2 = x so, as the above answer stated, (x+8)/2 is the answer.
What does y equals 3x plus y and y equals x-9 equal?
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
What is Y 6x - 9?
y=6x-9
How do you factor this Y3 plus 2y2 - 81y - 162?
y3 + 2y2 - 81y -162 = y2(y+2) - 81(y+2) =(y+2)(y2-81) = (y+2)(y-9)(y+9)
Is f of x equals negative 9 subtract x divded by 3 a inverse function?

Find the inverse of f x 3x plus 9?
f(x) = 3x + 9 y = 3x + 9 so 3x = y - 9 x = y/3 - 3 Therefore, the inverse function is g(x) = x/3 - 3
Y equals -x-9 function notation?
f(x)= -x-9
If f is a differentiable function such that f of 9 equals 2 and f' of 9 equals -2 then what is the linearization?
Use the point-slope form: y - y1 = m(x - x1). From the givens, y1 = 2, x1 = 9, and m = -2. Thus, y - 2 = -2(x - 9) = -2x + 18, or y = -2x + 20.

A father is thirteen times older than his son in 9 years he will be 4 times as old what age are they now?
Equation 1. f = 13sEquation 2. f + 9 = 4(s + 9) ie f + 9 = 4s + 36 ie f = 4s + 27Substitute for f: 13s = 4s + 27Subtract 4s from each side: 9s = 27Divide each side by 9: s = 3 so f = 39 ( in 9 years s = 12, f = 48)
