Answer:

(A)=-8

Explanation:

From the table, we can see for x= -4, the value of f(x) by substituting x=-4 is equal to -2,

For x=-1, the value of f(x) by substituting x=-1 is equal to 5,

For x=3, the value of f(x) by substituting x=3 is equal to 4 and

For x=5, the value of f(x) by substituting x=5 is equal to -8, thus

the value of f(5) by putting x=5 in the function will be equal to -8, therefore Option A is correct.

Answer: First option is correct.

Explanation:

Since we have given from the table that


\text{at }x=-4 ,f(x)=-2

it means at x=4 the value of function of x i.e. f(x) attains 2


\text{at }x= -1, f(x)=5

it means at x= -1 the value of function of x i.e. f(x) attains 5


\text{at }x=3 , f(x)=4

it means at x=3 the value of function of x i.e. f(x) attains 4


\text{at }x=5, f(x)=-8

it means at x=5 the value of function of x i.e. f(x) attains -8

so,


f(5)= -8

So, first option is correct.
