### how do you find the domain of the composite function when the f(x)=sqrt of x and g(x)=2x-5

When we look at each function we can see that g is defined for all values of x as a linear function. It is represented by an infinitely long straight line. But f is the square root of g(x) when the two functions are combined. We can't find the (real) square root of a negative number so the domain mu

### given the folowing piecewise function:

A. The domain is the range of values of x for which the function f(x) is defined. The lowest value for x is -4. There is no upper limit for x, because the function is defined for x>1. Therefore, the domain is x=>-4. B. The range of the function requires us to calculate its value over the do

### How are the locations of vertical asymptotes and holes different, and what role do limits play?

To talk about asymptotes and holes, you need pictures. These pictures are graphs of functions. The simplest function containing vertical and horizontal asymptotes is y=1/x, where x is the horizontal axis and y the vertical axis. The vertical asymptote is in fact the y axis, because the graph ha

### find domain,and locate intercepts; f(x)=x+3 f(x)=-2x-3 if x<-2 if x>=-2

I interpret this as f(x)=x+3 when x<-2 and f(x)=-2x-3 when x>-2, because the whole domain of x is covered by one or other function. Treating the functions separately, the domain of the first function is all x<-2; the domain of the second function is all x>-2. When x=0 we have the y or

### how do you write an equation for the linear function f with the given values?

Standard linear function is f(x)=ax+b where a and b are constants. Substitute each point into the function: 21=-2a+b, -35=5a+b. We need go no further because we have two linear equations and two unknowns. f(-2)-f(5): 56=-7a so a=-8. Now we can work out b: b=21+2a=21-16=5 so f(x)=5-8x. Qu
