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 x when f of x equals -7 and f of x is defined to be 2x plus 8?
f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5
Using f x 2x plus 7 and g x x-3 find f g x?
To find ( f(g(x)) ), we first need to determine ( g(x) ). Given ( g(x) = x - 3 ), we then evaluate ( f(g(x)) = f(x - 3) ). Next, substitute ( x - 3 ) into ( f(x) = 2x + 7 ): [ f(g(x)) = f(x - 3) = 2(x - 3) + 7 = 2x - 6 + 7 = 2x + 1. ] Thus, ( f(g(x)) = 2x + 1 ).
If f(x) x2 is vertically compressed by a factor of 7 to g(x) what is the equation of g(x)?
if f(x) = x² → g(x) = ⅟₇ x² = x² / 7
What is the inverse of f(x)2x-7?
To find the inverse of the function ( f(x) = 2x - 7 ), we first replace ( f(x) ) with ( y ): ( y = 2x - 7 ). Next, we solve for ( x ) in terms of ( y ): ( x = \frac{y + 7}{2} ). Finally, we swap ( x ) and ( y ) to express the inverse function: ( f^{-1}(x) = \frac{x + 7}{2} ).
What is the f of x which equals 7 divided by x?
It is f(x) = 7/x.
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 x when f of x equals -7 and f of x is defined to be 2x plus 8?
f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5
For f x 2x plus 1 and g x x2-7 find f g x?
f(x) = 2x + 1 g(x) = x^2 - 7 So f*g(x) = f(g(x)) = f(x^2 - 7) = 2*(x^2 - 7) + 1 = 2*x^2 - 14 + 1 = 2*x^2 - 13
Using f x 2x plus 7 and g x x-3 find f g x?
To find ( f(g(x)) ), we first need to determine ( g(x) ). Given ( g(x) = x - 3 ), we then evaluate ( f(g(x)) = f(x - 3) ). Next, substitute ( x - 3 ) into ( f(x) = 2x + 7 ): [ f(g(x)) = f(x - 3) = 2(x - 3) + 7 = 2x - 6 + 7 = 2x + 1. ] Thus, ( f(g(x)) = 2x + 1 ).
If f(x) x2 is vertically compressed by a factor of 7 to g(x) what is the equation of g(x)?
if f(x) = x² → g(x) = ⅟₇ x² = x² / 7
What is the inverse of f(x)2x-7?
To find the inverse of the function ( f(x) = 2x - 7 ), we first replace ( f(x) ) with ( y ): ( y = 2x - 7 ). Next, we solve for ( x ) in terms of ( y ): ( x = \frac{y + 7}{2} ). Finally, we swap ( x ) and ( y ) to express the inverse function: ( f^{-1}(x) = \frac{x + 7}{2} ).
What is the inverse of a function y1?
Definition of the inverse of a function.Let f and g be two functions such thatf(g(x)) = x for every x in the domain of g andg(f(x)) = x for every x in the domain of f.The function g is the inverse of the function f, and the domain of f is equal to the range of g, and vice versa.Example: Find the inverse of y1 = 2x + 7Solutiony1 = 2x + 7 interchange x and y;x = 2y1 + 7 solve for y;x - 7 = 2y1 + 7 -7 subtract 7 to both sides;x - 7 = 2y1 divide by 2 both sides;(x - 7)/2 = y1 replace y1 with y2;y2 = (x - 7)/2Thus, the inverse of y1 = 2x +7 is y2 = (x -7)/2Let's check if this is true according to the above definition:Let y1 = f(x) = 2x +7 and y2 = g(x) = (x -7)/21. f(g(x))= x ?f(x) = 2x + 7f((x - 7)/2) = 2[(x -7)/2] + 7 = x - 7 + 7 = x True2. g(f(x) = x ?g(x) = (x - 7)/2g(2x + 7) = [(2x + 7) - 7]/2 = 2x/2 = x True
If (x) -2x plus 5then f (7)?
f(7) = -9.
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
If fx -2x 1 and gx -4x then gf4?
f(x) = -2x + 1; g(x) = -4x; g(f(4)) = ? Solution: (g ° f)(4) = g(f(4)) = g(-7) = 28 f(x) = -2x + 1 f(4) = -2(4) + 1 f(4) = -7 g(x) = -4x g(-7) = -4(-7) g(-7) = 28
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.
