disc =b²-4ac=(-10)²-4×5×13=100-260=-160<0
t is imaginary.
So ball never reaches a height of 35 m
Answer:
a = 9, b = 3
Step-by-step explanation:
The exponential function is
y = a 
Find a and b by using the points it passes through
Using (0, 9 ) then
9 = a
(
= 1 )
a = 9
y = 9 
Using (3, 243 ) then
243 = 9b³ ( divide both sides by 9 )
27 = b³ ( take the cube root of both sides )
b =
= 3
y = 9
← exponential equation
