Which of the following describes the transformations of g(x)=-2 to the power of x+4 from the parent function f(x)=2 to the power of x?
shift 4 units left, reflect over the x-axis, shift 2 units down
shift 4 units left, reflect over the y-axis, shift 2 units down
shift 4 units right, reflect over the x-axis, shift 2 units down
shift 4 units right, reflect over the y-axis, shift 2 units down

i'm not doing your work for you, but

stretch - f(1/2x)
compress - f(2x)
reflect over x-axis - -f(x)
reflect over y-axis - f(-x)
left - f(x)+a
right - f(x)-a
up - f(x)+a
down - f(x)-a

and this isn't even hard, you could get the answer by plugging it in as a function on a graphing calculator

and by the way, you're going to have to use logarithms to solve that 2nd problem

this stuff really isn't that hard
if you actually bothered to dedicate any amount of time during the school year to get extra help, whether it be online, at the library, with a tutor, or even watching YouTube videos on the subject, you probably would have passed

this is the 21st century
you have the internet
use it

thats exactly what i mean. like i told you, i already passed the quiz (on my 3rd try!). but until you prove you can do a problem, you have not a centimeter of ground to stand on with your I'm-Smarter-Than-You! high horse

Like I've already said 2 times already, I'm not doing your work for you, and I don't believe you actually passed, but I'll gladly tell you how to solve it

You take the natural logarithm of the right side. ln(2^x) Since you're doing it to the right side, you have to do it to the left side. The entire point of using logarithms in the first place is so you can use the property where you're allowed to take an exponent and bring it out in front of the number. It's now x times ln2. Once you bring it out in front of the number, you can now divide on both sides by ln2 and solve for x
