A) the posible roots of the function f(x)=x⁴-3x³-5x²+21x+22 are:
=-1,+1,-2,+2,-11,+11,-22+22.
b)
one zero of the funtion can be: x=-1 ⇒y=0
(-1,0)c)
other zero of the funtion is: x=-2 ⇒y=0
(-2,0)d)
if x=0 then y=22
(0,22)
e) In the file is the graph.
X=28
It is simple just do percentases and then all the outside stuff
F ( x ) = - x² + 5 x + 4
between x = 3 and x = 5:
f ( 3 ) = - 3² + 5 · 3 + 4 = - 9 + 15 + 4 = 10
f ( 5 ) = - 5² + 5 · 5 + 4 = - 25 + 25 + 4 = 4
Average rate of change:
( 4 - 10 ) / ( 5 - 3 ) = - 6 : 2 = - 3 feet / sec
Answer:
x = -2
Step-by-step explanation:
8x + 2 + 4 = 2x - 6
8x - 2x = - 6 - 2 - 4
6x = -12
x = -12/6
x = -2
Simplify the answer so its ( x+1 over (x-2)(x-4) ) where the answer should be D all real numbers except 2 and 4.
hope it helped !!
