Which function represents a reflection of f(x) = Three-eighths(4)x across the y-axis? g(x) = NegativeThree-eighths (one-fourth)
nignag [31]

The function which represents a reflection of f(x) is

g(x) = Three-eighths (4)^{-x} ⇒ last answer

Step-by-step explanation:

Let us revise the reflection across the axes

  • If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x)
  • If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)

∵ Three-eighths = \frac{3}{8}

∴ f(x)=\frac{3}{8}(4)^{x}

∵ f(x) is reflected across the y-axis

- That means the sign of x coordinates of the points on the graph will

  change to opposite

∴ x will change to -x

∴ g(x)=\frac{3}{8}(4)^{-x}

The function which represents a reflection of f(x) is

g(x) = Three-eighths (4)^{-x}

An = a1 * r^(n-1)
a1 = first term = -5
r = common ratio = -4

so ur formula is : an = -5 * -4^(n-1) <==

The answer choices are -3, 3/2, 3, and -12/5.<br> thanks in advance!! :)
BabaBlast [244]

Answer:

<em>(C). {3} </em>

Step-by-step explanation:

\frac{x}{2(x+1)} = \frac{-2x}{4(x+1)} + \frac{2x-3}{x+1} ( x ≠ - 1 )

\frac{x}{2(x+1)} - \frac{2x-3}{x+1} + \frac{x}{2(x+1)} = 0

\frac{2x-3}{x+1} - \frac{x}{(x+1)} = 0

\frac{x-3}{x+1} = 0 ⇒ <em>x = 3</em>
