Step-by-step explanation:
<u>Given function:</u>
<em>See the graph below</em>
According to the graph we see that
The minimum is (-4, -1) and zero's are (-5, 0) and (-3, 0)
<u>Function is positive: </u>
<u>Negative:</u>
- When x is between -5 and -3
<u>Increasing:</u>
<u>Decreasing:</u>
Answer:
y - 6 = - 7(x - 3)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (5, - 8)
m = 
= 
= - 7
Use either of the 2 points for (a, b)
Using (3, 6), then
y - 6 = - 7(x - 3) ← in point- slope form
I would say the answer is c. only graph d ,, think of the line test to see if a graph is a function or not
Answer:
Step-by-step explanation:
P(x) = a(x - 2)2(x + 4), a ≠ 0
Use the given point (0,-10) to find a.
-10 = a(0 - 2)2(0 + 5) = a(4)(5) = 20a
a = -10/20 = -1/2
P(x) = (-1/2)(x - 2)2(x + 5)
You can expand this if you wish
