1, tim GTLN cua A=13/(x+5)^2+7
2, tim GTNN cua B=|x+2017|+(y+3)^2+2017
3, cho a-1/2=b+3/4=c-5/6 va 5a-3b-4c=46. Tim a,b,c.
a,Tim GTNN cua bieu thuc \(C=\left(x+2\right)^2+\left(y-\frac{1}{5}\right)^2-10\)
b,Tim GTLN cua bieu thuc \(D=\frac{4}{\left(2x-3\right)^2+5}\)
a, GTNN cua A=(2x+\(\frac{1}{3}\))-4-1
b,GTLN cua B=-(\(\frac{4}{9}\)x-\(\frac{2}{5}\))6+3
c,GTNN cua P=\(\frac{1}{2}\)+\(\sqrt{x}\)
d,GTLN cua Q=7-2.\(\sqrt{x-1}\)
(giai chi tiet giup minh)
a)tim GTNN cua
A=/x-2019/+(y-1)^2020-2
C=/x-3/+/x+4/-5
b)tim GTLN
B=3^2-4/x^2-25/
D=x-4/x-5
1) tim GTNN cua : a) /2.x-1/ +3 b) -4+ /x-5/ c)(2-5.x)2 +1
2) tim GTLN cua : a)5-/4.x-7/ b) -/x+5/- 6 c) 12- (4.x-5)2
HELP ME !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Tìm GTLN hoặc GTNN
a,h(x)=3.|x-2|+5
b,1/(x^2-2x+2)
Mink cần gấp lắm! Giúp mink nha
tim GTNN cua A=2+\(\sqrt{x-1}\)
a
Tim GTLN hoac( GTNN )cua bieu thuc ;
A=|2x-3/5|+1,(3)
B=1/3-|x-2| (B>0)00
C=-2|1/3x+4|+3/2
D=|x-3|+|x+2/3|
2/a/tim GTLN cua:
A=9-2.[x-3] (dau [ la GTTD)
b/tìm GTNN của:
B=[x-2]+[x-8] (dấu [ là GTTD)
