ANSWER
To graph the function
we need to plot some few points within one period. Since the interval is not given, we shall use
'
.
We plot the above points to obtain the graph as shown in the attachment.
Your answer is correct.
Also, the line rises 3 units up for every 1 unit it moves to the right, that means the rise/run (rise over run) is 3/1 which is equal 3 which means the slope must be equal to 3.
Inputting the equation 3x+4 into desmos creates an identically graph with the same y-intercept and x-intercept.
20. × 20
4. × 1
you also multiply 20×1 and 20×4 twice science both numbers are 20
Here are the steps to solving:
1) Write out problem 3.6+7.2k <25.2
2) Subtract 3.6 7.2k <21.6
3) Divide by 7.2 k <3
So k<3 would be your answer
