g(x) = 1/5 (5)^(x+4)
For the given function g, which of the following equivalent forms shows the y-coordinate of the y-intercept of the graph of y=g(x) in the xy-plane as a constant or coefficient?
A. g(x) = 125(5)^x
B. g(x) = 25(5)^(x+1)
C. g(x) = 5(5)^(x+2)
D. g(x) = (5)^(x+3)
Choice A is correct, but why?
Can you work through question 38 on Section 4 of practice test 1? Thanks 🙂
When you have exponents with the same base and you divide them, you subtract the exponents. So from what we’re given, we know that 2x – (x – y) = 1. We can solve that for y. 2x – (x – y) = 1 2x – x + y = 1 x + y = 1 y = (more…)

Question from March 2018 SAT: section 3 #15
This no-calc prompt is from the Daily Practice app:
The temp T in °C of a chilled drink after the drink has been sitting on a table for m min is represented by T(m) = 32 – 28*3^(-0.05m).
What is the best interpretation of the # 32 in this context?
A. The drink is originally 32°C.
B. Every 32 min, the temperature warms by 3°C.
C. After 32 min, the drink will fully warm to the ambient temp.
D. After the drink has been sitting for a very long time, the temp of the drink will approach 32°C.
