When it gets to zero or the intercept
factor
x=4(t^2-8t+9)
x=(4)(t-9)(t+1)
set to zero
t-9=0
t=9
t+1=0
t=-1, false, time cannot be negative
at t=9 seconds
Let the number 6 is multiplied by be y,
6 × y - 10 = 8
6y = 18
y = 3
answer is B
Answer: H. -2
Step-by-step explanation:
I am sorry but I cannot see the text on your screen if you could zoom in it would really help. : )
if the function is mirrored about the y axis, it is even
use -x in place of x and compare the equations
lets use 2 for x
so given formula would be 5-3(2) = 5-6 = -1
replace x with -x you would have 5-3(-2) =5-(-6) = 5+6 =11
since -1 does not = 11 the function is neither
even =f(x), odd = -f(x), neither f(x) doesn't equal -f(x)
example of odd:
f(x) = x^5 +x, replace x with -x
f(-x) = (-x)^5 +-x
=-x^5-x
=-(x^5+x)
=-f(x)
ODD
Example of even:
f(x) = 1-x^4
f(-x) = 1-(-x)^4
=1-x^4
=f(x)
EVEN
Example of Neither:
f(x) = 2x-x^2
f(-x) = 2(-x)-(-x)^2
=-(2x+x^2)
does not equal f(x)
NEITHER
