A function * f* with domain

*and codomain*

**X***is commonly denoted by*

**Y***, the elements of*

**f: X****→****Y***are called arguments of*

**X***. For each argument*

**f***, the corresponding unique*

**x***in the codomain is called the function value at*

**y***or the image of*

**x***, under*

**x***. It is written as*

**f***. One says that*

**f(x)***associates*

**f***with*

**y***or maps*

**x***to*

**x***. This is abbreviated by*

**y***.*

**y=f(x)**Questions

1) How to find the value of the function* f(x)* using Universal Math Solver ?

a) * f(-3) *,

**if f(x)=-3x²+4x-12****Answer**

and solve using UMS

The final answer is: **f(-3)=-51**

b)* f(π/3)*, if

**f(x)=sin2x-2cosx****Answer**

and solve using UMS

The final answer is: **f (π/3)=(√3-2)/2**

c) * f(√103)*,

**if f(x)=√(x²-3)**Answer

and solve using UMS

The final answer: **f(√103)=10**

2) How to find the table of values of the function * f(x)=-3x²+4x-12* from

*to*

**-3***using UMS calculator?*

**3****Answer**

Enter the function **f(x)=-3x²+4x-12**
