Given h (t) = negative 2 (t + 5) squared + 4, find h (negative 8).
–334
–14
45
445

-14

Step-by-step explanation:

h(-8) = -2 ( -8 +5 )^2 + 4

       =  -2 ( -3)^2 + 4

        = -18 + 4

        = -14

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
