Answer:
the domain of the function are {-3/2, 3/2, 3}
Step-by-step explanation:
f(x)=2x+1
range=-2, 4, 7
f(x)=-2
or, 2x+1=-2
or, x=-3/2
f(x)=4
2x+1=4
or, x=3/2
f(x)=7
2x+1=7
or, x=3
I need a image dude??? how am I suppose to find it
soln,
2x+2 = 3x - 52 [vertically opposite angles]
or, 2 + 52 = 3x - 2x
therefore, x = 54°
