Answer:
Step-by-step explanation:
f(x)=-2x³+x-3
-f(x)=2x³-x+3
f(-x)=-2(-x)³+(-x)-3
=2x³-x-3
it is not equal to f(x) or -f(x)
so it is neither even or odd.
it is neither even or odd.
f(x)=x^4-x^2+10
f(-x)=(-x)^4-(-x)^2+10=x^4-x^2+10=f(x)
it is an even function.
it is an even function.
f(x)=x^9-x^5+4x^3
f(-x)=(-x)^9-(-x)^5+4(-x)^3
=-x^9+x^5-4x^3
=-(x^9-x^5+4x^3)
=-f(x)
it is an odd function.
Answer:
20
Step-by-step explanation:
2m+10=4m
10=4m-2m
10=2m
m=5
SInce m=5, XC=4m=4*5=20
Personally its a bit unclear to me
but the solution for <span>x2 − 3x − 4 = x2 − 5x + 6 is x=5</span>
Answer:
35 cm
Step-by-step explanation:
Diameter of small pizza = 16
Let Diameter of large pizza = x
Diameter of small pizza = 2/5(x) + 2
2/5(x) + 2 = 16
(2x / 5) + 2 = 16
2x / 5 = 16 - 2
2x / 5 = 14
multiply both sides by 5
2x = 14 * 5
2x = 70
Divide both sides by 2
x = 70/2
x = 35
Diameter of large pizza = 35 mm
The answer to this question would be B. 5 2/4 hours. We can figure this out by adding up all of the times that were marked in the chart.
I hope this helped! :-)
