Identify the x- intercepts of the graphed function.

a. none

b. -1 and 1

it seems to obviously be 1 and -1, but on the previous question, the increasing intervals were listed as (-1, 0) u (1, infinity), suggesting that -1 and 1 are not included points of the function. would it still be -1 and 1?

edit: the intercepts are indeed -1 and 1, the correct answer is b.

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
