The essential thing about a function is that there should be only one value of $y$ for each value of $x$. Can you see one of those formulas where there might be more than one value of $y$ for a given value of $x$?Hi, I have a question and couldnt solve.
Can you help me?
Which one isnt function how i can show?
(a) $y = |x^3 + 5|$
(b) $y = x^2 + \sqrt(x) -\sin(x)$
(c) $y^2 = (x-5)^2 + 10$
(d) $y^3 = x + 4$
Thank you?
You should have been taught the 'vertical line test' .....Hi, I have a question and couldnt solve.

(b) y = x2 + sqrt(x) -sin(x)

Thank you?
