A-Level Maths B7-07 Graphs: Examples of Sketching the Modulus of a Linear Function

[gtxiwhe]

You deserve way more subs than u have atm. Thanks for making a fellow CIE A level student less stressed! Bless u

[keeweeow]

Thank you so much, I never knew u could complete the square with these to find the vertex

[sabirahmed]

Thank you very much sir for this spectacular way of making maths easy, you deserve more subs!

[lukeollerhead]

Youve just made these totally trivial. Nice!

[lol.]

You are saving me so much, deserve way more subs!

[izx]

thank you! i finally understand these now! :)

[IanNyondo]

Sir thank you so much made my life simple

This is the epitome of hero does't ware cape

[jazza]

can you make a video about writing modulus inequalities in a required form please (I got taught the rule |x-a|<b is equivalent to a-b<x<a+b, but I have no idea why)

[xaos]

For question 4 and 8 why does it turn into 5/8 and 3/5?

[lulumbimulenga]

Who knew math could be so easy. Thank you

Hi teacher how do i sketch the graph for Y=|1/2x-1| the completing square pov cant seems to work on this equation.

[adriankam]

for question eight, why cant the modulus be open downwards? As it is originally -5 at the very first

[fm_]

how did you know the gradient in q6 was 1?

[joshuakendle]

For question 7, shouldn't the vertex be (10, 8) instead of (-10, 8) because with 8 - abs(x+10) wouldn't the minus sign turn the +10 to -10 and then to get the vertex points you reverse the sign on the x value giving +10? Thanks

[harrysmith]

Can you put factors back into the modulus like when you took them out?

[jazza]

is it the same process if the question requires you to sketch a modulus of a y function?

[jazza]

what does b707 mean? I just came for OCR a2! Thanks for the vid anyway

[iuseyoutubealot]

How would you sketch a graph consisting of two modulus
