Answer:
y = 4
Step-by-step explanation:
The form of the exponential function is y = a
Use the given points to solve for a and b
Using (0, 4 ), then
4 = a (
= 1 ), thus a = 4
y = 4
Using (2, 196 ), then
196 = 4b² ( divide both sides by 4 )
49 = b² ( take the square root of both sides )
b = = 7
y = 4 ← exponential function
Step-by-step explanation:
there 5^(n+1) + 5^(n+2) = 5^n x 5^1 + 5^n x 5^2 breaking them as x^(a+b) = x^a x x^b
then taking common 5^n from both terms
