What is the vertical asymptote of X minus 7 divided by negative 2X plus 7 times 2X plus 5?

f(x)= (x-7) /(-2x+7)(2x+5) set -2x+7=0 -2x=-7 x=7/2 set 2x+5=0 2x=-5 x=-5/2 x=7/2 and x=-5/2 are vertical asymptotes.

For f x 2x plus 1 and g x x2-7 find f g x?

f(x) = 2x + 1 g(x) = x^2 - 7 So f*g(x) = f(g(x)) = f(x^2 - 7) = 2*(x^2 - 7) + 1 = 2*x^2 - 14 + 1 = 2*x^2 - 13

If f(x)2x-1 and g(x) x plus 2 fimd (f plus g)(x)?

h(x)=3x-4

How do you rewrite as a function of x using function notation for 2x plus 3y equals 4?

If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.

What can you say about the end behavior of the function f(x)- In (2x) plus 4?

You cannot because the function is not well-defined. There is no equality symbol, the function In(2x) is not defined.
