For this question, we need to use the Distributive Property:
2(x^2 – 1) = 2x^2 – 2
while
3x(x – 4) = 3x^2 – 12x

Michael Paul Goldenberg’s excellent comment was that the constant term must be -2 and that leads us right to the answer!  Thanks

Combine like terms and only the x^2 are combinable.
A way to check your work is to put  2(x^2 – 1) +  3x(x – 4) into Y1 and to put each multiple choice answer into Y2 and then compare to see if the tables for Y1 and Y2 are equivalent.

This is actually a reading question!
If x = 0, it will still cost 250
If x = 1, the cost should be 273 (250 + 23)
If x = 2, the cost should be 296 (250 + 23 + 23)
Try these values for x and you will find the answer 🙂

This question asks students to substitute or plug in -3 for x so 
g(-3) = -2(3)^2 + 3(-3) being careful about order of operations 🙂

Students can check their work by using the TI-84
