Let f(x) = -5x -4 and g(x) = 6x -7. Find f (x) + g(x)
–11x + 3
x + 3
–11x – 11
x – 11
Thank you, I will share with my granddaughter I am trying to help.
To find f(x) + g(x), we simply add the two functions together term by term.
f(x) = -5x - 4
g(x) = 6x - 7
Adding the x-terms, we have -5x + 6x, which simplifies to x.
Adding the constant terms, we have -4 + (-7), which simplifies to -11.
Therefore, f(x) + g(x) = x - 11.
To find f(x) + g(x), we need to add the two functions together.
f(x) = -5x - 4
g(x) = 6x - 7
To add the functions, simply add the corresponding terms. Since the term "-5x" in f(x) corresponds to the term "6x" in g(x), we will add these together:
-5x + 6x = x
Next, we add the constant terms "-4" and "-7":
-4 - 7 = -11
Therefore, f(x) + g(x) = x - 11.
So, the correct answer is x - 11.
well, just substitute in the values:
f(x)+g(x)
= (-5x-4)+(6x-7)
can you get it now?
