Question

For f(x) equals 2x+1 and g(x) equals x2 minus 7 Find (f+g) (x)

Answer 1

$(f+g)(x)=x^2+2x-6$

Step-by-step explanation:

We are given:

$f(x)=2x+1\\g(x)=x^2-7$

We need to find (f+g)(x)

Finding (f+g)(x):

$(f+g)(x)=f(x)+g(x)\\(f+g)(x)=2x+1+x^2-7\\Rearranging:\\(f+g)(x)=x^2+2x+1-7\\Adding\,\,like\,\,terms:\\(f+g)(x)=x^2+2x-6$

So, $(f+g)(x)=x^2+2x-6$
