For each graph, choose the function that best describes it.

Step-by-step explanation:

a). This graph represents a function with square root of x,

    f(x) =

b). This graph represents the reciprocal squared function with asymptotes as,

    Vertical asymptote x = 0

    Horizontal asymptote y = 0

    f(x) =

c). This graph represents a linear function (Straight line),

    f(x) = x

d). This graph represents the cubic function,

    f(x) = x³
