Please can someone help me.

Answer 1

Answer:

4

Step-by-step explanation:

Answer 2

Answer:

y = 4$(2)^{x}$

Step-by-step explanation:

An exponential function in standard form is

y = a$b^{x}$

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

Using (0, 4 ), then

4 = a$b^{0}$ [ $b^{0}$ = 1 ], so

a = 4

y = 4$b^{x}$

Using (1, 8 ), then

8 = 4$b^{1}$ = 4b ( divide both sides by 4 )

b = 2

y = 4 $(2)^{x}$ ← exponential equation
