As per the given question, the expression of the function
is as:

Now, as per the definition of zeros, the zero is that value of x which when plugged into the function should make the function zero (it is also called "making the function vanish"). <u>In our case, plugging in "zero values" of x should make the numerator zero without making the denominator zero.</u> Now, if we plug in the given values of x, which are x=-1, x=2 and x=4 in the function we see that the <u>numerator does not become a zero but the denominator does</u>.
Thus, x=-1, x=2 and x=4 are not the zeros of the function and therefore, Sue is wrong. However, we do have discontinuities at the aforementioned values of x because the denominator becomes a zero at those points and as per the definition of a discontinuity the denominator should be a zero at that point. Therefore, Ed is correct.
Answer:
2^31.
Step-by-step explanation:
2 * 2^30
= 2^1 * 2^30
= 2^31. (Law of indices)
Answer:
D=2.82
Step-by-step explanation:
Here we are given with two coordinates and asked to determine the distance between them.
Here we are going to use the distance formula, which is given as under

Where


Replacing these values in the distance formula






Hence the Distance is 2.82 units
Answer:
D) 65
Step-by-step explanation:
<1 = 11x + 5
<2 = 8x - 15
These angles are supplementary so,
11x + 5 + 8x - 15 = 180
19x - 10 = 180
19x = 190
x = 10
m<2:
8x - 15
8(10) - 15
80 - 15
65
