The domain for f(x) and g(x) is all real numbers. let f(x) = 3x^2 + x-7 and g(x) = x^2 + 4x-5

find (f-g)(x).

show work

Step-by-step explanation:

Here, the given functions are:

Now, as both the functions are POLYNOMIAL, and POLYNOMIAL FUNCTION FOLLOW THE  LINEAR TRANSFORMATION.

⇒(f-g)(x) = f(x) - g(x)

Now ,  

=

Or,  

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

what is the original number? you forgot to add it.
