A ball is thrown upward and outward from a height of 8 feet. The height of the ball, f(x), in feet, can be modeled by f(x)=−0.4x2+2.1x+8 where x is the ball's horizontal distance, in feet, from where it was thrown. Use this model to solve parts (a) through (c).

answer: i think it's a

step-by-step explanation:

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
