Question

If f(x) = 3x+5, g(x) = logx

Answer 1

Step-by-step explanation:

f(x))=4

g(3x+5)=4

log_5(3x+5)=4

5^4=3x+5

625=3x+5

620=3x

620/3=x

Answer 2

Correcct Question: If f(x) = 3x+5, g(x) = logx then find f(1) and g(1)

Given: Here we have given f(x) = 3x+5, g(x) = logx

To find: We have to  find f(1) and g(1)

Solution:

Here we have

f(x) = 3x+5

we will put x=1 to find f(1)

f(1)=3(1)+5

f(1)=8

g(x) = logx

we will put x=1 to find g(1)

g(1)=log1

g(1)=0

Final answer:

Hence the answer is f(1)=8, g(1)=0
