4. Using the Method of Completing the square, find the zeroes of the following function to the nearest hundredth.
F(x)=2x^2+12x+5

Given:

The function is:

To find:

The zeroes of the given function by using the Method of Completing the square.

Solution:

We have,

It can be written as:

By Method of Completing the square add and subtract square of half of coefficient of x in the parenthesis.

For zeroes, F(x)=0.

Taking square root on both sides, we get

and

and

Therefore, the zeroes of the given function are -0.45 and -5.55.

3x3 = 9 and 2x2 = 4

step-by-step explanation:

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
