Between which two ordered pairs does the graph of f(x) = one-halfx2 + x – 9 cross the negative x-axis?

Anit [1.1K]

Answer:

Step-by-step explanation:

we have that

$f(x) = x^2 + x - 9$

Using a graph tool

see the attached figure

The function represent a vertical parabola that open up

the vertex is a minimum-------> is the point (-0.5, -9.3)

The x-intercepts are the points when the y coordinate is equal to zero

The x-intercepts are the points (-3.5, 0) and (2.5, 0)

so

the function cross the negative x-axis at point

therefore, the answer is

(-4, 0) and (-3, 0)

Use the slider to change the value of m. As the value of m changes from 1 to 3, the graph . As the value of m changes from –6 to

vfiekz [6]

Answer: 1) gets steeper

2) gets less steep

3) Negative.

Step-by-step explanation:

Since, the slope intercept form of a line is,

y = mx + c

Where m represents the slope of the line,

If m = positive , then the line has positive slope,

While If m = negative then the line has negative slope.

Now, The line having the maximum absolute value of m is called stepper line,

Here, the equation of line is,

y = mx

⇒ m is the slope of the line,

1) Since, |1| < |3|

⇒ When m changes from 1 to 3 then the line gets steeper.

2) Since, |-6| > |-1|

⇒ When m changes from -6 to -1 then the line gets less steep.

3) If m = Negative

Then the slope of the line is negative.

fill inbthe bubble next to all the double facts you could use to find the sum of 3+2? A 2+2 B 5+5 C 3+3 D 1+1

GarryVolchara [31]

Answer:

Option A , C and D are correct.

Step-by-step explanation:

Double Facts states that the additions in which a number is added to itself.

then; by definition of double facts

Use Double facts to find the sum of 3 + 2

3 + 2

=3 + (3 - 1)

= 3+ 3 - 1

= 6 - 1

= 5

similarly,

3+2 = (1+2) + 2 = 1 + 2+2 = 1 + 4 = 5

Also;

3 + 2 = 3 + (1+1) = 3 +1+1 = 5

therefore, the double facts that used to find the sum of 3+2 are; 2+2 , 3+3 and 1+ 1.

Identify the explicit function for the sequence in the table.

juin [17]

14 - 9 = 5
19 - 14 = 5
24 - 19 = 5
29 - 24 = 5

It is an arithmetic sequence with differences, b = 5 and a = 9
a(n) = a + b(n - 1)
a(n) = 9 + 5(n - 1)

The answer is B
