A cat jumps off a three foot high kitchen counter at an initial velocity of 2 feet per second. The function h(t)=−16t2+vt+s models the cat's height (in feet) above the kitchen floor, where v is the initial upward velocity of the cat in feet per second.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

step-by-step explanation:

yes   because as the functions are graphed they eventually will intersect unless otherwise
