The exponential function is
Step-by-step explanation:
The form of the exponential function is , where
- a is the value of y when x = 0
- b is the rate of change
∵ The form of the exponential function is
∵ The function goes through points (0 , 12) and (2 , 768)
- Substitute the coordinates of the first point to find the value of a
∵ x = 0 and y = 12
∴
∵
∴ 12 = a(1)
∴ a = 12
Substitute the value of a in the form of the function
∴
- Substitute the coordinates of the second point to find the value of b
∵ x = 2 and y = 768
∴
- Divide both sides by 12
∴ 64 = b²
- Take √ for both sides
∴ b = 8
- Substitute the value of b in the form of the function
∴
The exponential function is

Answer:
The square root of 64 is 8
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
A linear function describes a straight line with constant gradient. Hence A is the answer as it has a constant gradient of -1 .
B is wrong as the graph has an undefined gradient.
C is wrong as it has an increasing gradient.
D is wrong as it does not have a constant gradient too.
Answer:
y = 1/2x - 7
Step-by-step explanation:
y = 1/2x + b
-4 = 1/2(6) + b
-4 = 3 + b
-7 = b
