If g(x) = 2x-1 and h(x) = sqrt x find (g o h)(9)

(g o h)(9) =5

Step-by-step explanation:

Given :

To Find: (g o h)(9)

Solution:

To find (g o f)(x)=g(h(x))

Now substitute x = 9

[tex]g(h(9)) = 5/tex]

(g o h)(9) =5

Hence the value of  (g o h)(9) is 5

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
