In Problems 57-64, use a graphing utility to solve each system of equations. Express the solution(s) rounded to two decimal places.
$\left\{\begin{array}{l}y=x^{2 / 3} \\ y=e^{-x}\end{array}\right.$

Key Concepts

Rounding Numerical Approximations

Rounding numerical approximations involves adjusting a numerical value to a specified degree of precision, such as two decimal places. This process is important in practical computations to simplify numbers and communicate results clearly, especially when dealing with measurements or when exact values are not needed.

Power Functions with Fractional Exponents

Power functions with fractional exponents are expressions where the variable is raised to a fraction. They generalize the concept of roots and powers, representing functions that may exhibit unique properties like reduced symmetry or restricted domains. Understanding these functions is important for analyzing their behavior and accurately graphing them.

Exponential Functions

Exponential functions are mathematical expressions in which a constant base is raised to a variable exponent. These functions are known for their rapid growth or decay and are fundamental in modeling real-world phenomena such as population growth, radioactive decay, and interest calculations.

System of Equations

A system of equations consists of two or more equations with the same set of variables. The objective is to find the values of these variables that simultaneously satisfy all equations in the system. Solving systems can involve methods like substitution, elimination, or graphical approaches where the solution corresponds to the intersection points of the equations' graphs.

Graphical Solution of Equations

Using a graphing utility to solve equations involves plotting each equation on the same coordinate system and visually or numerically identifying their intersection points. This method is especially useful when equations are non-linear or when an exact algebraic solution is difficult to determine. It relies on understanding the behavior of the functions involved and approximating the points where their graphs meet.

Intersection of Curves

The intersection of curves refers to the points on a graph where two or more functions cross each other, meaning that they share the same x and y coordinates at those locations. In the context of solving systems of equations graphically, these intersections represent the solutions that satisfy all equations simultaneously.
