If you transform y = 2x^2 into y = 10x^2, which option below describes the effect of this transformation on the graph of the quadratic function along the y-axis?

Don't know how the multiple choices are worded, but you can match the choices with these words:
it is stretched along the y axis by a factor of 5. 
vertically stretched by a factor of 5,
horizontally compressed by a factor of 5

(answer 2 )i’m very smart that’s how i know the answer.
