Question

Select the correct answer. if f(x) = x^1/2– x and g(x) = 2x^3 –x^1/2-x find f(x) – g(x).

Answer 1

f(x) - g(x) =  $-2x^{3}+2x^{1/2}$

Step-by-step explanation:

Given :

• f(x) = $x^{1/2} -x$
• g(x) = $2x^{3} -x^{1/2} -x$

f(x) - g(x) = ($x^{1/2} -x$) - ( $2x^{3} -x^{1/2} -x$)

⇒ ($x^{1/2} -x$$-2x^{3}+x^{1/2} +x$)

⇒ $-2x^{3}+2x^{1/2}$

f(x) - g(x) =  $-2x^{3}+2x^{1/2}$
