Graph h(t)=-2(t+5)^2+3, find h(-8)
2 answers:
Answer:
h(-8)=-15
Step-by-step explanation:
Substitute t=-8
h(-8) =-2(-8+5)^2+3
=-2(-3)^2+3
=-2(9)+3
=-18+3
=-15
<em>h(-8) = - 15</em>
Step-by-step explanation: <em>h(t) = - 2(t + 5)² + 3</em>
<em>replace </em><em>t </em><em> with </em><em>- 8 </em>
<em>h(-8) = - 2(- 8 + 5)² + 3</em>
<em>h(-8) = - 2(-3)² + 3</em>
<em>h(-8) = -2×9 + 3</em>
<em>h(-8) = - 18 + 3</em>
<em>h(-8) = - 15</em>
