Question

if the graph of function y= 2x2 -5 is traslated down 4 unites, what is the equation of the new function ?A.y= 2x^2-1B. y =-2x^2 -9C. y =2x^2+1D. y = 2x^2-9

Answer 1

`y=2x^{2\text{ }}-\text{ 5}`

If y = 2 x ^2 - 5 is translated downwards by 4 units then

y = f (x - 4) = 2x^2 - 5 - 4

y = 2x^2 - 9
