f(x)=3x-5 g(x)=2-x^2

Question

Evaluate the expression and Find the domain

Answer 1

The domain is the x values where the graph exists.

 

f(x) = 3x - 5    is a linear function.  The domain is all real numbers.

 

g(x) = 2 - x²    is a quadratic function.  The domain is all real numbers.

 

 

To evaluate the expression, you can plug in any value of x to determine f(x) and g(x).
