Answer:
False
Step-by-step explanation:
The absolute value shows the distance a value is from 0, which is always positive.
The trick here is to substitute points given

substituting point A x-value =b

turns out false since (b,a*b^b) !=(b,0)
substituting point B x-value=0

turns out true since (0,a)=(0,a)
we already got f(x) at x =0 which is not the point (0,0)
so c is false
substituting D x-value=a

hence B is the correct answers
Answer:
These are simultaneous equations.They have to be solved like this:
2x-y=3 -y=3-2x 2x-3= -x
y= -x y= -(3-2x) 3x= 3
y=2x-3 x=1
Step-by-step explanation:
The value of x equals to 1
