A.
9
B.
45
C.
53
D.
65

Answer 1

45

Explanation:

A function is given to us .And we need to find its value at x = 11. So on substituting x = 11 , we have ,

The given function :-

`:\implies` f(x) = 5(x-2)

On putting x = 11 :-

`:\implies` f(11) = 5 ( 11 - 2)

`:\implies` f(11) = 5 × 9

`:\implies` f(11) = 45

Hence the value at x = 11 is 45 .

Answer 2

B

Explanation:

Substitute x = 11 into the expression

5(11 - 2)

= 5 × 9

= 45 → B
