Let f and g defined as f(x)=x-5 and g(x)= x^2-1 . Find f•g ? ​

Sagot :

solution:

Let f and g be defined as f(x) = x-5 and g(x) = x²-1.

Then, we find f-g.

So, we have:

(f - g)(x) = f(x) - g(x)

f(x) - g(x) = (x-5) - (x² - 1)

f(x) - g(x) = -x² +1 +x - 5

Thus, we obtain,

f(x) - g(x) = -x² +x - 4
