Please help me thank you

b = 20 when a = 8.

Step-by-step explanation:

For this problem, we will simply plug the value of a=8 into the given equation for b, to find the value of b.

b = [ (a)^2 / 4 ] + 4

b = [ (8)^2 / 4 ] + 4

b = [ 64 / 4 ] + 4

b = [ 16 ] + 4

b = 20

Hence, when the value of a=8, then the value of b=20.

Cheers.

20

Step-by-step explanation:

b = a^2/4 +4

Let a =8

b = 8^2 /4 +4

  = 64/4 +4

   = 16 +4

   = 20

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
