Ignore my answer! Please help! The parabola has a vertex of (4,7) and passes through the point (2,-5). Write an equation using vertex form: y=a(x-h)2+k. What is the value of “a” in this equation.

answer4 to the second power is 16

and 4 to the third power is 64,

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
