Answer:
k = 3
Step-by-step explanation:
y = kx² - 3x
Since the points lie on the graph we can substitute the values of x and y that's
( 2 ,6) into the equation to find k.
We have
6 = (2)²k - 3(2)
6 = 4k - 6
4k = 6 + 6
4k = 12
Divide both sides by k
That's
[tex] \frac{4k}{4} = \frac{12}{4} [/tex]
We have the final answer as
k = 3
