How do you graph linear functions? Example: To graph a function such asf(x) = y = 2x + 7, we can select a table of values, plot and connect the points. To fill the table, we choose values forxand use the function to get the values ofyas shown in the following table. x -3.5...

This article will show by an example how we can write an equation for the line that has a given slope and passes through a given point.Step 1 We will find the Linear Function whose graph has a slope of (-5/6), and passes through the point (4,-8). Please click on the image to...
答案—2 解析一 在一次函数y=2xa中令y=0则2xa=0,x= 在一次函数y:3x+b中,y=0则0=x+3, x=-b/3 由题可知=,且两图象交于x轴上原点外的一点, a0,且ba 因此可设.m0)a1)a=2m,b=—3m a/2=-b/3=m( ∴a/(a+b)=(2m)/(2m-3m)=-2 (无面线相支)解析 在一次函数y=2xa中令y=0则...
The graph of the equation y2 = x3 2x2 + x looks like: Since many vertical lines cut this graph at more than one point, this is not the graph of a function. 1.2. Examples: Example 1.2. Linear Functions: A linear function is a function of the form f(x) = mx + b (where m ...
Function $f(x)=\sqrt{1-x}$Value of $a$ $a=0$ 2Use a graphing utility to graph the function. Then graph the linear and quadratic approximationsandin the same viewing window. Compare the values of f, P_1, and P_2 and their first derivatives at x= a. How do the approximations ...
A linear equation in slope-intercept form is written as {eq}y=mx+b{/eq} where {eq}m{/eq} is the slope of the line and {eq}b{/eq} is the {eq}y{/eq} intercept, the point at which the graph of the function crosses the {eq}y{/eq}-axis. A li...
