Question

A variable y is partly constant and partly varies as the square of x.When x =2,y=b and when x=3,y=10
a.find the equation connecting x and y
b.what is the value of when x=4
c.find the value of x when y =5

Answer 1

y = a + bx^2
Using the given values,
a+4b = 6 ??
a+9b = 10
Solve for a and b, and then you can answer the questions
