Please can someone help me.

y = 4

Step-by-step explanation:

An exponential function in standard form is

y = a

Substitute points from the graph into the equation to find a and b

Using (0, 4 ), then

4 = a [ = 1 ], so

a = 4

y = 4

Using (1, 8 ), then

8 = 4 = 4b ( divide both sides by 4 )

b = 2

y = 4 ← exponential equation

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
