What is f of x equals x to the 4th power minus 5x if f equals 3?

The idea is to replace every "x" by "3", and then do the calculations.


What is the value of f of x plus 7 if f of x equals -5x-9?

Let, f (x) = - 5x - 9 Therefore, f(x) + 7 = - 5x - 9 + 7 f(x) + 7 = - 5x - 2


What is gf 4 if f x equals 5x and g x equals 3x - 7?

f(x)=5x, g(x)=3x-7 gf(x)= = g(f(x)) = g(5x) = 3*(5x) - 7 = 15x-7 So gf(4) = 15*4-7=53


What is the inverse of f of x equals 5x plus 4?

No, f(x) is not the inverse of f(x).


How do you find the rate of change for 5x plus 3y equals -2?

Rearrange for y, let f(x) = y, and find the derivative of f(x) with respect to x: 5x + 3y = -2 y = -(5x+2)/3 = f(x) df/dx = -5/3


Rewrite fx equals 5x plus 2?

f(x)=5x+2


How do you solve f of x equals x squared plus 5x plus 1?

f(x) = x2 + 5x + 1 The roots of this equation are x = -0.2087 and x = -4.7913 (approx).


How do you complete the inverse of fx?

Follow this example. f(x) = (x+3)/5 To find its inverse, write y=f(x) y= (x+3)/5 Interchange x and y x = (y+3)/5 solve for y in terms of x 5x=y+3 y=5x-3 The inverse of f(x) is f^-1(x) = 5x-3


if f(x)=x+8 and g(x)=-4x-3 find (f-g)(x)?

To find (f-g)(x), we need to subtract g(x) from f(x). So, (f-g)(x) = f(x) - g(x). Substituting the given functions, we get (f-g)(x) = (x+8) - (-4x-3). Simplifying this expression, we get (f-g)(x) = x + 8 + 4x + 3 = 5x + 11. Therefore, (f-g)(x) = 5x + 11.


Let f x equals x2 plus 5x plus 3 Find f 2?

If I understand this right... f(x) = x2 + 5x + 2 f(x) is a function, in this case a function of x. Using this function, you can say... f(g) = g2 + 5g + 2 f(pi) = pi2 + 5pi + 2 All we're doing is substituting whatever's in the brackets on the other side. Thus... f(2) = 22 + 5*2 + 2


What is the answer to d equals 6 and f equals 3?

You've given the answer yourself. d=6 and f=3.


if f(x)=4x-8 and g(x)=5x+6 find (f+g)(x) if?

(f+g)(x) = 4x + 8 + 5x -6 => (f+g)(x) = 9x + 2
