Question

how would you find the x an y intercepts of y=xsqrrt16-x^2 ?

Answer 1

the y intercepts is when x = 0
so plug in x = 0 into the function and work it out

Answer 2

to find the x intercepts sole

xsqrrt16-x^2 = 0

Answer 3

you will put y as equal to zero
and then \[\sqrt{16}-x^{2}\]
x will be 4 and -4

Answer 4

i'm assuming there are parentheses around the 16 - x^2

Answer 5

the x intercepts will be 4 and -4 but also 0.

Answer 6

xsqrrt(16-x^2) = 0

x = 0 , x^2 - 16 = 0

x^2 = 16 so x = 4 ,-4

Answer 7

y intercept = 0* sqrt16 = ?

Answer 8

yint=0 ?

Answer 9

yes

Answer 10

thank you so much!
