Answer:
x-int=-8, y-int=2,-4
Step-by-step explanation:
for the x-int
you set x to 0 then solve the equation to get -8
for the y-int
you set y(or in this case f(x)) to 0 then solve. You solve this by spilting this into 2 linear equations; x-2=0 and x+4=0, then you solve them both to get the two y-intercepts, 2 and -4
To graph a piecewise function, simply graph both functions. However, if, for the function it says something like x>0, erase the function for the values of x not greater than 0. The domain is what the x values can be, and the range is what the y values can be.
Answer:
Step-by-step explanation: ok so they sold 9 book marks for every 2 books right?
so you would put 72 over nine like a fraction, then you would put 2 over X like another fraction.
Then cross multiply. 72*x=72x
9*2=18
72 divided by 18 = 40
I hope this helps
Im going to guess you want a sinusoidal function. Its been a while but I can tell you most of it
(443-28)/2 is the amplitude
28 minutes is the period
40-28 is the horizontal shift
(443-28)/2+28 is the vertical shift
Answer: yes
Step-by-step explanation: 30 is one more then 29
