The graph of the function f(x) = (x – 4)(x + 1) is shown below. Which statement about the function is true? The function is incr
Akimi4 [234]
Given the graph of the function f(x) = (x - 4)(x + 1).

From the graph, it can be seen that the graph of the function describe a parabola facing up with the vertex at point (1.5, -6.25).
The x-intercepts of the graph are at points (-1, 0) and (4, 0) while the y-intercept is at point (0, -4)

The vertex of a parabola is the point in the parabola where the graph of the function stops decreasing and starts increasing, or vice-versa.

Thus, the function stops decreasing at point (1.5, -6.25) and then starts increasing, this means that for values of x < 1.5 the function is decreasing and since 0 < 1.5, hence, the function is decreasing for the values of x < 0. Hence, the statement that "the function is increasing for all real values of x where x < 0" is not true.

Similally, Given that the function stops decreasing at point (1.5, -6.5), this means that for values of x < 1.5 the function is decreasing and since -1 < 1.5, hence, the function is decreasing for the values of x < -1.
Thus, the statement that the function is increasing for all real values of x where x < –1 and where x > 4  is not true.

<span>With the explanations given above, it can also be seen that the statement that "the function is decreasing for all real values of x where –1 < x < 4" is also not true.</span>

Michael has $10 to put in a savings account . He has two options for a saving account : Option 1 will add $ 100 to his account e
nekit [7.7K]

Answer:

Option 1:

He starts with $10, and for each week, we add $100

Then his balance as a function of weeks will be:

f(w) = $10 + $100*w

option 2.

Again, we start with $10, and for each week that passes this is doubled, then the equation will be:

g(w) = $10*(2)^w

Now, we want in week w = 7 to have at least $700, then we need to replace w by 7 in both equations and see which one is better.

option 1:

f(7) = $10 + $100*7 = $710

With option 1 he will have enough

option 2:

g(7) = $10*(2)^7 = $1280

Again, he will have more than $700 in week 7, and we can clearly see that this option is better.

What is the quotient of 4 1/4 / 2 1/5
Snezhnost [94]

The quotient for the given mixed fraction is 1.9318

Step-by-step explanation:

Step 1; First we must convert the mixed fractions into improper fractions. To do that the whole number is multiplied with the denominator and add with it the numerator while the denominator does not change. To convert this fraction 4\frac{1}{4} we multiply 4 with 4 and then add 1 and keep the 4 as the fraction's denominator so we get \frac{17}{4}. Similarly, we get the improper fraction \frac{11}{5} for converting the mixed fraction 2\frac{1}{5} .

Step 2; After conversion, it's just a matter of division. The fraction \frac{17}{4} equals 4.25 while the denominator \frac{11}{5} equals 2.2. Dividing 4.25 by 2.2 we get 1.9318.
