Evaluate f(−10)f(-10)f(−10) where f(t)=−10t2+20t+80f(t) = -10t^2 + 20t + 80f(t)=−10t2+20t+80:
f(−10)=−10(−10)2+20(−10)+80f(-10) = -10(-10)^2 + 20(-10) + 80f(−10)=−10(−10)2+20(−10)+80
=−10(100)−200+80= -10(100) - 200 + 80=−10(100)−200+80
=−1,000−200+80=−1,120= -1,000 - 200 + 80 = -1,120=−1,000−200+80=−1,120
