### Function Notation:Definitions & Evaluating at a Number

Now you say "f (x) = 2x + 3; find f (1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one"). In either notation, you do exactly the same thing:you plug 1 in for x , multiply by the 2 , and then add in the 3 , simplifying to get a final value of +1 .

### Solve Nonlinear equations x^3-6=0 Tiger Algebra Solver

x 3 - 6 = 0 Step 2 :Solving a Single Variable Equation :2.1 Solve :x 3-6 = 0 Add 6 to both sides of the equation :x 3 = 6 When two things are equal, their cube roots are equal. Taking the cube root of the two sides of the equation we get:x = 6 The equation has one real solution This solution is x = 6 = 1.8171 Solve Properties of a straight line f(x)=x^2 7,f(3)= Tiger 3.3 Solve f-x = 0. Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK). "y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis. In this formula :

### Solve inequalities with Step-by-Step Math Problem Solver

Example 3 Solve 2x + 1 = x - 2. We want to obtain an equivalent equation in which all terms containing x are in one member and all terms not containing x are in the other. If we first add -1 to (or subtract 1 from) each member, we get. 2x + 1- 1 = x - 2- 1. 2x = x - 3. If we now add -x to (or subtract x from) each member, we get. 2x-x = x - 3 Solve system of nonlinear equations - MATLAB fsolvefun is a function that accepts a vector x and returns a vector F, the nonlinear equations evaluated at x. The equations to solve are F = 0 for all components of F. The function fun can be specified as a function handle for a file. x = fsolve(@myfun,x0)
