tbh h.c chhbv. yea I can
the end behavior is that it goes positive and both ends (we look at x^4 ) and put in -inf and + inf and get +inf both times)
to get the y intercept let x=0 y intercept =144
to find the x intercepts we factor and find the zeros
using graphing technology we plot the function
we look at the ends of the graph if it goes down it goes to - inf, if it goes up it goes to + inf
the y intercept is where x=0
there x intercepts are where it crosses the x axis on the plot (there should be 4 unless some are imaginary)
Answer:
d.
Step-by-step explanation:
if x varies directly as y,
x = ky
8 = 12k
12k = 8
k = 8/ 12
k = 2/3,
x = 2/3 y
now substitute the value of any of the numbers of each pair, and check if it works:
for e.g, find x when y = 15
x = 2/3y
x = 2/3 × 15
x = 10
since you obtain x = 10 when y = 15, the pair is a possible corresponding value of x and y. now do the same for the rest .
ii) x = 2/3y
x = 2/3 × 3, when y = 3
x = 2
hence, this is also a possible pair of x and y values.
iii) x = 2/3y
x = 2/3 × 9 when y = 9
x = 6
again, a possible pair of x and y values.
iv) x = 2/3y
x = 2/3 × 20 when y = 20
x = 40/3
here, when y = 20, x is not 15. it is 40/3.
thus, it can be determined that this is not a possible pair of x and y values.
please try to understand and have a great day!
