Question

Let f(x) = x2 - 1 and g(x) = 2x - 3. Find the new function and write it in simplest form

Answer 1

Answer:

Option C is the correct answer

${x}^{2} + 2x - 4$

Step-by-step explanation:

$f(x) = {x}^{2} - 1 \\ g(x) = 2x - 3 \\ (f + g)(x) = f(x) + g(x) \\ (f + g)(x) = {x}^{2} - 1 + 2x - 3 \\ \purple{ \boxed{ \bold{ (f + g)(x) = {x}^{2} + 2x - 4}}}$
