✽ Hello there! ✽
4x+9<21
Move all the constants (numbers) to the right, using the opposite operation:
4x<21-9
4x<12
Divide both sides by 4 to isolate x:
x<3
<h2>Therefore, x<3 ✔︎</h2>
Hope this helps!
~Just a felicitous girlie

The parent linear function is y = x
A reflection in the x-axis is denoted by - f(x), so the answer is false
This answer is c (x-4)(x+4)
