Doing a bit of guess and check, we can notice that the amount of leaves is one less than the number of inches of vine. Writing it out, we get x-1=y (the amount of inches-1=the amount of leaves)

Let f(x)= 5/x and g(x)=2x^2+5x What two numbers are not in the domain of f o g?

Igoryamba

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)

$f(g(x))= f( 2x^2+5x)$

replace 2x^2+5x in f(x)

$f(g(x))= f(2x^2+5x)=\frac{5}{2x^2+5x}$

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

$2x^2+5x=0$

$x(2x+5)=0$

x=0 and 2x+5=0 (subtract 5 on both sides)

2x= -5 (divide by 2 on both sides)

x=-5/2
