Question

If g(x)=2x + 1, find g(a + h)- g(a).



2h

2h + 2

h + 1

Answer 1

2h is the correct answer

Answer 2

g(a+h) means you put (a+h) anywhere there is an x, and g(a) means you put a everywhere there is an x, so your equation should look like \[2(a+h)+1-(2a+1)\]
Distribute and combine like terms
