Answer:
<em>Option C</em>
Step-by-step explanation:
If we were to consider this question as a whole, all we are being asked is to find an expression equivalent to 2 * ( 5 )^x, as all other function are expressed in the same f ( x ) format. Now all we have to thing about are the expression that = 2 * ( 5 )^2x;

Hope that helps!
Answer:
(a) 
(b)
Step-by-step explanation:
1:16 or 5:80, if you're simplifying then all you do is divide denominator by numerator. then that's your simplified ratio
Check the picture below.
they're at a 3:1 ratio, thus, 3 times.
I’m fairly sure it is the last one. But the pictures are hard to see. 3/2 is the slope and -1 is the y intercept. Find the point at (0,-1) , the y intercept. Then go up 3 and over 2 to find the next point
