Find an equation that is used in real life to solve problems. tell what your equation does. identify the variables and what the different parts of the equation represent. then determined which one is the dependent and the independent variables. create a couple questions that could be answered using the equation and find the answer to your question

If we in the following equation y=x+7 assigns a value to x, the equation will give us a value for y. ... We could instead have assigned a value for y and solved the equation to find ... the independent variable, and the other variable is the dependent variable, ... A function is an equation that has only one answer for y for every x

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
