Question

1. Given the function f(x) = 4x ‐ 8
a. Find the rate of change between the two stated values for x: 5 to 7
b. Find the equation of a secant line containing the given points:(5,f(5)) and (7,f(7))

2. Graph the following function using transformations. Be sure to graph all ofthe stages on one
graph. State the domain and range.
For example, if you were asked to graph y= x^2+1
using transformations, you would show the
graph of y = x^2

and the graph shifted up 1 unit. Please do not show only the final graph.
y= -sqrt x-6

Answer 1

This one is hard..

Answer 2

i think for 1 a) it is asking u fro the slope of the line. u know the two points; one is at x = 5 and y = 12 and the other at x = 7 and y = 20. so use the slope equation

Answer 3

For 1 b) the secant line is just the linear line passing through both points, which u can fine using the info from part 1 a and the general equation form of y = mx + b
