fx=x+4 g(x)= x^2+3x-1x find g(1)

Step-by-step explanation:

Rephrasing the question:

Given:

and

Find g(1).

Solution:

Firstly, we need to replace f(x) with the function in g(x) to get a function, g(x), in terms of x, so we have:

To get g(1), we replace "x" with "1", shown below:

The value is

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
