Evaluate the function f(x)=3x2−2x+1 f(x) = 3x^2 - 2x + 1 at x=2 x = 2 .

Solution

To evaluate the function f(x)=3x2−2x+1 f(x) = 3x^2 - 2x + 1 at x=2 x = 2 : f(2)=3(2)2−2(2)+1 f(2) = 3(2)^2 - 2(2) + 1 =3(4)−4+1 = 3(4) - 4 + 1 =12−4+1 = 12 - 4 + 1 =9 = 9 Solved on Solvelet with Basic AI Model

DefinitionFunction notation is a mathematical convention used to represent functions and their evaluations. It consists of a function name and has independent variable or variables inside parenthesis. Function notation is a way to write and type functions, represent the relationship between variables, and evaluate functions at certain points in their domain. It gives a notational and standardized method defining mathematical operations and transformations. Function notation is widely used in algebra, calculus, and mathematical modelling to define functions, express mathematical relationships, and solve equations. Example: If the function f(x)=2x+1, then f(3)=2(3)+1=7.
