Albedos of Various Earth Surfaces

An albedo is the amount of light reflected from a surface divided by the amount of light falling on the surface. The amount is typically measured in watts per square meter. The table shows the minimum and maximum albedos for different types of surfaces on Earth.
In a desert region, the amount of sunlight falling on a surface with an area of one square meter is 1,000 watts. Which of the following could be the amount of sunlight, in watts, reflected from this one-square-meter surface?

For a certain group of fish, the graph models the relationship between body length L, in centimeters (cm), and tail area A, in square centimeters $open parentheses c m to the power of 2 end exponent close parentheses$ , where $6 less or equal than L less or equal than 34$ . Which equation represents the relationship between body length and tail area?

Solving quadratic equations using a graph is an effective method for locating estimated solutions or roots for quadratic equations or functions.
The real roots of a quadratic function might be zero, one (repeated), or two. Finding the origins involves solving a quadratic equation with the right-hand side equal to zero, such as ax² + bx + c = 0.
Points to consider to solve a quadratic equation using a graph :
• Rearrange the equation so that one side corresponds to the graphed function.
• Plot the function y= the other side of the equation.
• To find the solutions, draw vertical lines down to the x-axis from the intersection points.
