Please answer soon I have been very confused for this entire unit and we have a test worth 50% of our grade tomorrow. I need HELP!!!!
Thank you so so so much
Thank you for the opportunity to help you with your question!
Three very important
types of equations.
Using Differences to
Determine the Model
By finding the differences between the dependent values, we
can determine the degree of the model for the data.
If the first difference is the same value, the
model will be linear.
If the second difference is the same value, the
model will be quadratic.
If the number of times the difference has been
taken exceeds five, the model may be exponential or some other special
Has an x with no exponent.
y = 10x + 9
y = ½x
5x + 9y = 2
Has an x2 in the equation.
5y = 2x2 + 8x – 6
2y = 4x2 + 10
5x2 + 10y = 50
Has an x as the exponent.
y = 6x + 7
y = 102x
2x + 4y = 20
