Question

If f (x)=x^3 find the value of f (5)-f (1)/5-1

Answer 1

Answer:

31

Step-by-step explanation:

f(x)=x^3 = f(5)-f(1)/5-1

5^3-1^3/5-1

124/4

31

Answer 2

Answer:

124 is the value $f(5) - \frac{f(1)}{5} - 1$

Step-by-step explanation:

Explanation:

Given, f(x) = $x^3$

And we need to find the value of $f(5) - (\frac{f(1)}{5} ) - 1$

So, we need to first find the value of f(5) and f(1).

Step 1:

From the question, f(x) = $x^3$

So, f(5) = $(5)^3$ = 125.

and f$\f(1)$ = $(1)^3$ = 1.

Now , put the value of  f(5) and  f(1) in $f(5) - \frac{f(1)}{5} - 1$ we get,

⇒$f(5) - \frac{f(1)}{5} - 1$

⇒ $f(5) - \frac{f(1)}{5} - 1$ = 125 - $\frac{1}{5}$ -1=  $\frac{125 (5)- 1-5}{5}$ = $\frac{625 - 6}{5}$

⇒$f(5) - \frac{f(1)}{5} - 1$ = $\frac{619}{5}$ = 123.8 = 124.

Final answer:

Hence, the value of $f(5) - \frac{f(1)}{5} - 1$ is 124.
