Answer:
-1, -2
Step-by-step explanation:
Since multiplication by 0 will result in 0, any value of x resulting in 0
(-1+1)(-1+2)=0
0x1=0
(-2+1)(-2+2)=0
-1x0=0
Answer:
to grow bacterial cultures
G ( x ) = 2 - ( x - 7 )²
g ( x ) = 2 - ( x² - 14 x + 49 )
g ( x ) = 2 - x² + 14 x - 49
g ( x ) = - x² + 14 x - 47
The maximum of the function is at:
x= - b / 2 a
x = - 14 / ( - 2 ) = 7
Therefore the function is increasing form x ∈ ( - ∞, 7 ) and decreasing for x ∈ ( 7, +∞ ).
Answer:
C. increasing, x < 7; decreasing x > 7.
