Part A: In (0,4) and (1,8), as x increases from 0 to 1, y increases from 4 to 8. The slope of the line connecting these 2 pts. is (8-4) / (1-0), or 4. Now do the same thing for the 2 pts (1,8) and (2, 10). You will find that the slope in the 2nd case is different. Thus, the 3 given pts do NOT lie on a straight line. Function is non-linear.
Part B: an example of a non-linear function would be y = 2x^2 - 5. You can tell immediately from that exponent, 2, that this function is non linear.
An ex. of a linear function would include x to the 1st power only: y = 3x - 7.
Answer:
Step-by-step explanation:
Let x represent the number if people that she can invite.
Yolanda is doing a party for her daughter. She has spent $130 on the venue and Will spend $18 per person for food. This means that the total amount that she would spend if she invites x persons is
130 + 18x
She wants to spend no more than $500. Therefore, inequality to help her determine how many people she can invite would be
130 + 18x ≤ 500
Question 1) x=4
