Question

if (x)=3x+10 g(x)=x-2 find f(g(5) is??? pls answer this urgent ​

Answer 1

Step-by-step explanation:

x=3x+10

x-3x=10

2x=10

x=5

g(5)=x-2

5g=x-2

g=5-2/5(because the x value is5)

g=3/5

Answer 2

SOLUTION

GIVEN

f(x) = 3x + 10 , g(x) = x - 2

TO DETERMINE

f(g(5))

EVALUATION

Here it is given that

f(x) = 3x + 10 , g(x) = x - 2

Now

g(5) = 5 - 2 = 3

Thus we get

f(g(5))

= f(3)

= ( 3 × 3 ) + 10

= 9 + 10

= 19
