<span>The y-intercept of is .
Of course, it is 3 less than , the y-intercept of .
Subtracting 3 does not change either the regions where the graph is increasing and decreasing, or the end behavior. It just translates the graph 3 units down.
It does not matter is the function is odd or even.
is the mirror image of stretched along the y-direction.
The y-intercept, the value of for , is</span><span>which is times the y-intercept of .</span><span>Because of the negative factor/mirror-like graph, the intervals where increases are the intervals where decreases, and vice versa.
The end behavior is similarly reversed.
If then .
If then .
If then .
The same goes for the other end, as tends to .
All of the above applies equally to any function, polynomial or not, odd, even, or neither odd not even.
Of course, if polynomial functions are understood to have a non-zero degree, never happens for a polynomial function.</span><span> </span>
So last week Paul worked 2.5x this week's hours, so he worked a total of 2.5x15= 37.5 hours last week.
Answer:
7×17/49
Step-by-step explanation:
90/7 × 4/7
90×4 / 7×7
360/49
7 17/49
The cost depend on the number pencils, so the cost is the y and # of pencils is the x
Same as for question 7
To graph, the length depend on the time, so length is y, time is x
6. Linear
7. Not
Standard form : Ax + By = C
y - 4 = 0
y = 4...this is a horizontal line and a horizontal line has a 0 slope
so in standard form, ur equation is : 0x + y = 4
