Question

22. Given f(x)=10x & g(x)=2x-4

Find the value of f(1)
Find the value of g(3)
Find the value of f(1)+g(3)
Find the value of f(10)-g(0)

Answer 1

f(1)=10

g(3)=2

f(1)+g(3)=12

f(10)-g(0)=104

Explanation:

f(x)=10x

g(x)=2x-4

f(1)=10×1=10

g(3)=2×3-4=2

f(1)+g(3)=10+2=12

f(10)-g(0)=(10×10)-(2×0-4)=100+4=104
