Question

y=2^x-5-9

Five points with coordinate whole numbers . Ex x=5, y=-8

Answer 1

y = 2^(x-5) - 9

x = 1

y - 2^-4 - 9 = 1/16 - 9 = - 8 15/16

(1, - 8 16/16)

x = 2

y = 2^-3 - 9 = 1/8 - 9 = - 8 7/8

(2, - 8 7/8)

x= 3

y = 2^-2 - 9 = 1/4 - 9 = - 8 3/4

(3, - 8.75)

x = 4

y = 2^-1 = 1/2 - 9 = -8.5

(4, - 8.5)

x =5

y = -8

(5, - 8)

Answer 2

I will assume the function is:

Let x = 5, then, since 2⁰ = 1, y = -8: Point = (5, -8)

Let x = 6, then, since 2¹ = 2, y = -7: Point = (6, -7)

Let x = 7, then, since 2² = 4, y = -5: Point = (7, -5)

Let x = 8, then, since 2³ = 8, y = -1: Point = (8, -1)

Let x = 9, then, since 2⁴ = 16, y = 7: Point = (9, 7)
