A:
Answer:The function is linearStep-by-step explanation:* Lets check from the table the type of the function- At first check if it is linear or not- The points are:   (165 , 198) , (168 , 201.6) , (170 , 204) , (172 , 206.4) , (175 , 210)* Find the slope for each two points if the value of the slop is  constant, then the function will be linear∵ The slop = (y2 - y1)/(x2 - x1)∴ m1 = (201.6 - 198)/(168 - 165) = 1.2∴ m2 = (204 - 201.6)/(170 - 168) = 1.2∴ m3 = (206.4 - 204)/(172 - 170) = 1.2∴ m4 = (210 - 206.4)/(175 - 172) = 1.2∵ m1 = m2 = m3 = m4# Note: You can use any to points to find the slope you will   have the same value∴ The graph of the points is a line with slope 1.2* The function is linear
