Which function represents a reflection of f(x) = three-eighths(4)x across the y-axis? g(x) = negativethree-eighths (one-fourth) superscript x g(x) = negative three-eighths(4)x g(x) = eight-thirds(4)-x g(x) = three-eighths(4)–x

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

g(x) = Three-eighths  ⇒ 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 =

∴

∵ 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

∴

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

g(x) = Three-eighths

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
