y is directly propotional to x-3 to the whole square then y=k(x-3)²
at y=16 and x=1
we get value of k is -8
hence by put value of k we get
y=-8(10-3)
we get value of y is -56
at y=16 and x=1
we get value of k is -8
hence by put value of k we get
y=-8(10-3)
we get value of y is -56

Answer: 196
Step-by-step explanation: y is directly propotional to (x-3)^2
y ∝ (x-3)^2
y = k(x-3)^2
16 = k(1-3)^2
After caculating you should get this
4k = 16
And the answer for K will be 4
then we will put the value of K in the equation y = k(x-3)^2 with x=10
y = 4(10-3)^2
y = 4(7)^2
y = 4(49)
y = 196
The final answer is y = 196
