Which equation has a graph that lies entirely above the x-axis?
y = –(x + 7)2 + 7
y = (x – 7)2 – 7
y = (x – 7)2 + 7
y = (x – 7)2

The graph that lies entirely above x-axis is:

(Option 3 is correct )

Step-by-step explanation:

" The graph must lie entirely above x-axis means that there is no negative solution of the equation or no zero solution i.e. y must always attain positive value for any x "

the equation that satisfies this condition is:

Hence, option 3 is correct.

Because in

option 1:

for x=0 we have y= -42

Hence option 1 is incorrect some points will lie below x-axis.

option 2:

when x=7 y= -7

Hence some points will lie below x-axis.

Hence option 2 is incorrect.

option 4:

When x=7 y=0.

Hence this point lie on the x-axis.

Hence, option 4 is incorrect.

2 2/3 hours duhh silly

step-by-step explanation:

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
