Answer:
the value of x will be 24
Step-by-step explanation:
Answer:
<u>Given function:</u>
- f(x) = (-x + 2)(x + 1)(x +2)
<u>We can rewrite it as:</u>
- f(x) = - (x - 2)(x + 1)(x +2)
<u>Zeros are:</u>
- - (x - 2)(x + 1)(x +2) = 0
- x - 2 = 0 ⇒ x = 2
- x + 1 = 0 ⇒ x = -1
- x + 2 = 0 ⇒ x = -2
As leading coefficient is negative the function is decreasing.
As the function is of degree 3, it is odd.
<u>Considering the above two factors we can define the shape of the graph:</u>
- It is decreasing function with one local minimum and one local maximum.

Time taken to ride 1 mile=7 min.
So time taken to ride 4 mile=4×7=28min.
Answer:
Rachel is not correct
Step-by-step explanation:
It is true that the set of integers includes negative numbers, where the sets of whole or natural numbers do not. However, any rational, irrational, or real number can be negative. -5.5 is a rational number, but <em>it is not an integer, because it has a fractional part</em>.
The value 9 because you add
