Answer:
Step-by-step explanation:
The zeros are where the graph intersects the x-axis
x = 0
x = 2
x = 4
------------------------
Extra Credit
Note x = 2 is a double zero since it touches, but does not cross the x-axis
The equation is
y = -x(x - 2)²(x - 4)
Answer:
first option
Step-by-step explanation:
If ( x + h) is a factor of f(x) then f(- h) = 0 , then
If (x + 1) is a factor of f(x) then f(- 1) = 0
f(- 1) = 7 - 5(- 1)³ - 10(- 1)² + 2(- 1)
= 7(1) - 5(- 1) - 10(1) - 2
= 7 + 5 - 10 - 2
= 12 - 12
= 0
Since f(- 1) = 0 then (x + 1) is a factor of f(x)
Answer:
185/24
Step-by-step explanation:
Convert both to fractions with the same denominator first.
35/8= 105/24
10/3= 80/24
105/24+80/24
= 185/24
