The function h(t)=-16t2+144 represents the height, h(t), in feet, of an object from the ground at t second after its dropped. a realistic domain for this function is what out of the options : a) -3

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

answer: your answer is a
