For f(x)=2x+1 and g(x)=xsquared-7 find (f-g)(x)
1 answer:
Answer:
<em>(f-g)(x) = - x² + 2 x + 8</em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given f(x) = 2 x +1
g(x) = x² - 7
(f-g)(x) = f(x) - g(x)
= (2 x + 1) - ( x² -7)
= - x² + 2 x + 1 + 7
= - x² + 2 x + 8
<em>(f-g)(x) = - x² + 2 x + 8 </em>
