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

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
