we know that
The x-intercept is the value of the variable x when the value of the function is equal to zero
so
In the table we have
is a x-intercept, because
For the value of the function is equal to zero
is a x-intercept, because
For the value of the function is equal to zero
therefore
<u>the answer is</u>
the continuous function in the table has two x-intercepts
Option c : 9 is the answer.
Explanation:
The expression is
We need to determine the subtracted value of the expression.
From the expression we can see that the expression contains two negative signs.
To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.
This means
Thus, the expression can be written as
Adding the two numbers, we get,
Thus, the value of the expression is 9.
Hence, Option c is the correct answer.
