Answer:
Option A is correct.
The function for the given graph is;
Step-by-step explanation:
An exponential function is in the form of ......[1] where a is the initial value and b≠ 0 , b >1 .
Given two points as shown in figure i.e,
let A = (0, 2) and B = (1,8)
Substitute these points in equation [1] we have;
For A = (0,2)
= a
⇒ a = 2
and
for B = (1, 8)
or
Substitute the value of a=2 in above equation to solve for b;
2b = 8
divide both sides by 2 we get;
b = 4
Then, the function for the graph is, y=
Answer:
1) Option c) is correct ie., 5 real and o non-real
2) Option b) is correct ie., (4, ,
, 2,2)
Step-by-step explanation:
Given polynomial function is
To find zeros equate f(x) to zero ie.,
By synthetic division
| 1 0 -3 0 -2
-1 | 0 -1 1 2 2
|_________________
1 -1 -2 2 0
Therefore x=-1 is a zero
| 1 -1 -2 2
1 | 0 1 0 2
|___________________
1 0 -2 0
x=1 is the zero
and
Option c) is correct ie., 5 real and o non-real
2) Given polynomial function is
To find zeros equate f(x) to zero ie.,
(or)
or
Therefore x=4, of multiplicity of 2 and x=2 multiplicity of 2
Option b) is correct ie., (4, ,
, 2,2)
