Understanding the Function Table

The given function table represents a relationship between two variables, x and y, where x is expressed as a function of y. The function is given by the equation x = 5y^2 + 3. The table contains three rows, each representing a specific value of y and the corresponding value of x.

y	x
0	3
2	23
4	?

Analyzing the Function Equation

To find the missing value in the table, we need to analyze the function equation x = 5y^2 + 3. This equation represents a quadratic function, where the coefficient of y^2 is 5 and the constant term is 3.

Substituting y = 4 into the Function Equation

To find the missing value in the table, we need to substitute y = 4 into the function equation x = 5y^2 + 3.

x = 5(4)^2 + 3 x = 5(16) + 3 x = 80 + 3 x = 83
