Question

b) If = {(2,4),(4,5), (7,10)} and g(x) = {(4,2), (5,2), (10,2)}. Show that gof is a constant
function.
​

Answer 1

Answer:

I hope it will help you!!

Step-by-step explanation:

Soln,

f(x) = {(2,4),(4,5), (7,10)} and

g(x) = {(4,2), (5,2), (10,2)}

We know,

gof (x) = { (2,2) ,(4,2) ,(7,2) }

here,

gof (x) = 2

when x = 2

gof (x) = 2

when x = 4

gof (x) = 2

when x = 7

gof(x) = 2

Therefore, gof is a constant function.
