Answer:
±[tex]\sqrt{\frac{y-4}{b} }[/tex] = x
Step-by-step explanation:
to solve y = 4 + bx², we want x alone, so lets subtract 4 from both sides to start
y - 4 = bx² < now divide both sides by b to get x alone
[tex]\frac{y-4}{b}[/tex] = x² < we can square root both sides to get rid of the x² in the equation
±[tex]\sqrt{\frac{y-4}{b} }[/tex] = x
the equation above is our answer. looking at the answer choices, they look a bit messed up, but I would have to say the answer is A if that line above the b is a division symbol
