Determine if the following functions are one-to-one by inspecting their graphs using the Vertical line test (VLT) and the Horizontal Line Test (HLT). You do not need to sketch the graphs. 1.) Y=5x-2 VLT: HLT: One-to-One: 2.) Y= 1/x VLT: HLT: One-to-One:

1. Graph the following function on the coordinate plane. y = -x² - 8x - 17 y

Given data of height, x and stories, y is of six notable buildings in a city. height numbers: 768, 628, 518, 511, 491, 478 and stories numbers: 52, 48, 46, 43, 37, 35.  What is the scope and y intercept of this? Round the scope to three decimal places as needed. Round the y-intercept to two decimal places as needed.

The value of y varies directly with the value of x , Which function represents the relationship between x and y if y=7/3 when x=21?

Sketch the graph of y = √x.

Use the graph of y = f(x) to answer the following ( b. Determine (3).

f) The prices y of a Christmas tree based on the height x if: a 6-foot tree costs between $20 – $50 an 8-foot tree costs between $25 – $75 an 11-foot tree costs between $100 and $200 a 13-foot tree costs $300 or more function or not?

Complete the following steps for the given function, interval, and value of n. a. Sketch the graph of the function on the given interval. b. Calculate Ax and the grid points xo, X1, ..., Xn-
