Question

Let f(x) = 2x+5. If x * 0 then find +2)-r(3)/x​

Answer 1

Step-by-step explanation:

f(x+2)−

x

f(2)

=

x

2x

2

+9x−9

Step-by-step explanation:

Given: f(x) = 2x + 5 and x ≠ 0

To find: f(x+2)-f(2)/x

Consider,

f(x+2)-f(2)/x

= 2(x+2)+5-\frac{2\times2+5}{x}2(x+2)+5−

x

2×2+5

= 2x+4+5-\frac{9}{x}2x+4+5−

x

9

= 2x+9-\frac{9}{x}2x+9−

x

9

= \frac{2x^2+9x-9}{x}

x

2x

2

+9x−9

Therefore, f(x+2)-\frac{f(2)}{x}=\frac{2x^2+9x-9}{x}f(x+2)−

x

f(2)

=

+9x−9
