Answer and Step-by-step explanation:input and output are essentially variablesinput is the variables in the equation that you put into the numberthe output is the answer you get once you put in the input (I hope that helps, usually i am good at explaining using numbers than in words)ex#1: 10=output input=xf(x)=10, find x when f(x)=2x+6so when you are solving the input, you just are solving for for a variable (in this case it's x)so... 10=2x+6 x=2But if you are looking for the outputs, you just plug in the variable's value and solve in the equation.ex#2: Find [tex]f(x)= 2x^2+3x+5[/tex] when f(2)So what you do to find the output(answer), you just plug in the number that is in the f(x), in this case it's 2[tex]2(2)^{2}+3(2)+5=(8+6+5)= 19[/tex]
