Question

What are the coordinates of the vertex of the graph of f (x)=2x - 3|?

Answer 1

Answer:

$(\frac 32, 0)$

Step-by-step explanation:

I'm assuming that there was a | at the beginning so it's $f(x) = |2x-3|$. With this kind of plots you get angular points where the graph of the "original" function - ie the one without the absolute value - would cross the x-axis. In this case, when $2x-3 = 0 \rightarrow x= \frac32$
