Question

Which function equation is represented by the graph?



​ f(x)=5(53)x ​

​ f(x)=5(52)x ​

f(x)=5(25)x

​ f(x)=5(35)x ​

Answer 1

Solution:

As we can see from the graph given, the curve cuts Y axis, passes through (0,5) , (2,1) and appears parallel to X axis.

Also, you can see that curve is decreasing and after it crosses the point (4,0) it becomes parallel to X axis.

As you can see from the graph , the general equation of curve will be  

f(x) = $a^{-x}$

There is no function in the option given which has a negative exponent.

Answer 2

Answer:

f(x)=5(2/5)^x
