Write the function for the graph. f(x)
10-
(1,8)
(0,4)
A. f(x) = 4 . (2)
B. f(x) = 8. (4)*
C. f(x) = 4. (8)*
D. f(x) = 2 · (4)

answer is (a)

Step-by-step explanation:

first thing we should find the equation which is f(X)=a*b^x

so the always will be the y intercept no matter what

now time to find b if graph that is shown start from 1 until the end of line which is in the graph so you will find it 8 now divide 8 by 4 so 8/4=2

so final equation will be f(x)=2*(4)

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
