graphing transformation, mcq (1 Viewer)

[Masaken]

How to go about solving this? Answer is (D) but I don't understand the transformation of f(2x) in the first place...

 

[mmmmmmmmaaaaaaa]

Because it is a -f(x), that would indicate that the function has flipped, eliminating a and b

To get from f(x) to f(2x) ... that means it dilates horizontally by a factor of 0.5

 

[carrotsss]

And because of the 1 it gets moved up by 1

Also I remember doing this question haha, Sydney Tech 2019?

Fun fact: in addition to the 2019 Sydney Technical High School paper, this question also appeared in a 2009 VCE paper.

Same lol I’ve just got a fat stack of past papers printed out and I’ve been just spamming those everyday… I still don’t feel fully prepared even after like 6 past papers, I’m so terrified for the exam.

I've finished 14 papers or so and those don't include the ones from my school (was saving them for last and starting them all today), the fear of getting a bruh mark after all that terrifies me to this day

Yup.

Gah, I’m terrified, at least I’ll have longer to prepare right? I’ve only really had a week and a half to prepare for the prelims because of my religion trials, so that’s my excuse haha

Yeah same, I’m scared I’ll just go into the exam room and make tons of mistakes… I really want to keep my 1st ranking it’s so stressful
