Y varies partly as x and partly as the square of x when x =2 and y=14 and when x=5 y=65, express y in terms of x hence find y when x=2

Answer 1

y = mx^2 + b
using the given data, you have
4m+b = 14
25m+b = 65
Now solve as usual for m and b
Not sure why you want to find y when x=2, since you already told us it was 14.
