Graph the function <br> Is it a, b, c or d?
Jobisdone [24]

Answer:

D

Step-by-step explanation:

(the line is a / shape, so the slope is positive)

(the line crosses the y axis at (0,-2))

(using the above information, we can conclude that the equation is y=2x-2)

or

slope = m = rise/run = 2/1 = 2

y=mx+b

y=2x+b

Choose any point on the line) (1,0)

0=2(1)+b

b=-2

y=2x-2

Answer the following.
nexus9112 [7]

Step-by-step explanation:

1075 students were asked how close they live to the college. The table shows the results below with some values missing. Enter the correct values in the boxes remembering to use the % symbol where necessary.

<u>20 to 25: </u>given 20%

20% of 1,075 = 215

<u>15 to 19: </u>given 12%

12% of 1,075 = 129

<u>10 to 14: </u>given 516 students

(516/1,075)*100 = 48%

<u>5 to 9: </u>given 162 students

(162/1,075)*100 = 15.07%

<u>< 5: </u>given 53 students

(53/1,075)*100 = 4.93%

Given the function f(x) = −3x3 + 9x2 − 2x + 3, what part of the function indicates that the left end starts at the top of the gr
shutvik [7]

Answer: The correct option is, The coefficient of the first term.

Step-by-step explanation:

The given function is,

f(x)=-3x^3+9x^2-2x+3

End behavior of the polynomial function : It is defined as the graph of f(x) as x approaches +\infty and -\infty.

The end behavior of the graph depends on the leading coefficient and degree of the polynomial.

As, the degree of the polynomial is '3'. So, the leading coefficient will determine the structure of the graph.

Therefore, the coefficient of the first term will indicate that the left end starts at the top of the graph.

The graph is also shown below.
