If f(x)=3x+2.5, determine the value of f(3)

f(3)=11.5

Step-by-step explanation:

In order to solve this equation, all you have to substitute the value inside of the parenthesis with the value of x in the equation after the equals sign. SO...

f(3)=3x+2.5

f(3)=3(3)+2.5

f(3)=9+2.5

f(3)=11.5

Hope this helps!

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
