Q. Find the function that doubles in value for every interval and at x = 3, y = 24

y = 3(8x)
y = 3(2x)
y = 2(3x)
y = 8(24x)
Q. Find a function that decreases by three for every interval and at x = 1, y = 5

y = 3x – 5
y = 8x – 3
y = -x + 8
y = -3x + 8
y = x-3 + 8
Q. Find the exponential function that fits the following table of data: {0;2 , 2;98 }

y = 2(7x)
y = 7(2x)
y = 14(2x)
y = 49(2x)
y = 2(14x)
Q. Find the exponential function that fits the following table of data: {1;-6 , 2;-18 }

y = 2(3x)
y = -6(3x)
y = 2(-3x)
y = -2(3x)
y = 6(-2x)
