The number inside parenthesis is the x value.

Look up the provided X value and see what the corresponding Y value is, which would be the answer.

In the given table when X is 5, the f(x) = -8

Answer:

The correct option is 1. The value of f(5) is -8.

Step-by-step explanation:

In the given table the first column represents the values of x and the second column represents the values of function f(x) at difference values of x.

From the given table it is clear that

The value of function is -2 at x=-4. It means f(-4)=-2.

The value of function is 5 at x=-1. It means f(-1)=5.

The value of function is 4 at x=3. It means f(3)=4.

The value of function is -8 at x=5. It means f(5)=-8.

The value of f(5) is -8. Therefore the correct option is 1.

$s = ut + \frac{1}{2} a {t}^{2} \\ s = 10( \frac{1}{2} ) + \frac{1}{2} ( - 2) {( \frac{1}{2}) }^{2} \\ s = 10( \frac{1}{2} ) + \frac{1}{2} ( - 2)( \frac{1}{4} ) \\ s = 5 + ( - 1)( \frac{1}{4} ) \\ s = 5 + ( - \frac{1}{4} ) \\ s = 5 - \frac{1}{4} \\ s = \frac{20}{4} - \frac{1}{4} \\ s = \frac{19}{4}$
