Question

if f(x)=5x-5,g(x)=sin^3x+2cos^3x. the value of f(g(f(1))) is​

Answer 1

Answer:

5

Explanation:

f(1) =5*1-5=0

g(f(1))=g(0) = sin^3 (0) + 2cos^3 (0) = 0 +2=2

f(g(f(1)))=f(2)= 5*2-5=5

Answer is 5.

Answer 2

Answer:

$f(g(f(1)))=5$

Explanation:

We are given the expression :

• $f(x)=5x-5$
• $g(x)=\sin^3x+2\cos^3x$

To Find:

The value of $f(g(f(1)))$

Solution :

According to the given functions

$f(1)=5(1)-5=0$

$g(f(1))=g(0)=\sin^3 0+2\cos^3 0$

$g(f(1))=g(0)=0+2(1)=2$

$f(g(f(1)))=f(2)=5(2)-5=5$

Hence we get the result that

$f(g(f(1)))=5$
