Answer:
two number not included in domain are x=0 and x=-5/2
Step-by-step explanation:
Let f(x)= 5/x and g(x)=2x^2+5x
WE need to find out the excluded value in the domain of f o g
f o g is the composition of functions
f o g= f(g(x))
lets plug in g(x) in f(x)
![f(g(x))= f( 2x^2+5x)](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D%20f%28%202x%5E2%2B5x%29)
replace 2x^2+5x in f(x)
![f(g(x))= f(2x^2+5x)=\frac{5}{2x^2+5x}](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D%20f%282x%5E2%2B5x%29%3D%5Cfrac%7B5%7D%7B2x%5E2%2B5x%7D)
here we have 2x^2+5x in the denominator
to find the numbers that are in domain we set the denominator =0 and solve for x
Because when denominator becomes 0 the function is undefined
![2x^2+5x=0](https://tex.z-dn.net/?f=2x%5E2%2B5x%3D0)
![x(2x+5)=0](https://tex.z-dn.net/?f=x%282x%2B5%29%3D0)
x=0 and 2x+5=0 (subtract 5 on both sides)
2x= -5 (divide by 2 on both sides)
x=-5/2
