Hope this helps!
We are to find the graph which best represents the given function:
f (x) = 5 (2)^-x
To be able to solve this, let us write the function of each graph mathematically
and select the correct one.
Graph A:
function f of x equals 5 multiplied by 2 to the power of negative x =>
f (x) = 5 (2)^-x
Graph B:
function f of x equals 5 multiplied by 2 to the power of x => f (x) = 5
(2)^x
Graph C:
function f of x equals 10 to the power of x => f (x) = 10^x
Graph D:
function f of x equals 10 to the power of negative x => f (x) = 10^-x
Therefore based on the mathematical interpretations above, only Graph A is
similar to the given function. Hence the correct answer is:
Graph A
Answer:
(a) 16 ft/s
(b) 1.5 s
Step-by-step explanation:
(a) Put 1 where t is in the expression and do the arithmetic:
-32×1 +48 = 16 . . . . feet per second
__
(b) Use the hint and solve for t:
-32t +48 = 0
t -1.5 = 0 . . . . . divide by 32
t = 1.5 . . . . . . . . add 1.5
The ball reaches its maximum height after 1.5 seconds.
