Question

where does the function intersect the x-axis ?

equation below ..

Answer 1

\[y=\sqrt{x}\]

Answer 2

the function intersect the x-axis when the value of y=0, so substitute y=0 to the eqauation and solve for x..

Answer 3

\[0=\sqrt{x}\] but then would you square root it to get the radical away ? or how would you do it ?

Answer 4

square both sides. 0^2 is just 0, so x=0 is the answer.

Answer 5

okay cool. i wasn't so sure

Answer 6

it happened to me in the past too. you can manipulate 0 just like any other number.

Answer 7

so the function intersects with the x-axis @ (0,0) ?

Answer 8

yup. graph it and see.

Answer 9

oh yes. thanks again(:
