Answer: 1/27
Step-by-step explanation:
I have a solution here however with a slight change in the equation:
<span> f(x)=3x^2-6x+1
My solution is:
</span>The domain is all real numbers--there are no restrictions like a square root or variable in the denominator
<span>
this is a U shape parabola and you want to find the bottom point, it is at the vertex </span>
<span>x=-b/2a =- (-6) /2 (3) =1 </span>
<span>f(1) =3(1)^2 -6(1) +1 =3-6+1 =-2 </span>
<span>the minimum is (1, -2) </span>
<span>so the range is all real numbers >= -2
</span>
By examining my solution, you could just answer the problem on your own! I hope it helps!
I think the correct answer is D
Answer:
its sqrt(x)/5-2/5, x is greater than or equal to 0

Answer: Each daylily cost $3 and each ornamental glass cost $8.
Build two equation's: (Let 'd' be daylilies, 'o' be ornamental grass)
$118 on 2 daylilies and 14 bunches of ornamental grass.
$98 on 14 daylilies and 7 bunches of ornamental grass.
Make d subject for first equation.
2d + 14o = 118
2d = 118 - 14o
d = (118 - 14o)/2
d = 59 - 7o
Insert this into second equation.
14(59 - 7o) + 7o = 98
826 - 98o + 7o = 98
-91o = -728
o = 8
Find value of d:
d = 59 - 7o
d = 59 - 7(8)
d = 3
