If f(x)=2x+7 and g(x)=x-1; find f(g(-1))

Step-by-step explanation:

3

Step-by-step explanation:

Given twee functions f and g. The question is to find f(g(-1)). If you interpret f(g(-1)) then you can look at it, as two different questions on one. So split it up into two separate questions and answer them seperately.

1. Find the result of substituting the number x= -1 in g.

g(x)=x-1 substitute x= -1

g(-1) = -1 -1 = -2

2. Find the result of substituting the number x= -2 in f.

f(x) = 2(x) + 7 substitute x= -2

f(-2) = 2*-2 +7 = -4 + 7 = 3

So now you have found the result of f(g(-1)), which in this case turns out to be 3.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
