in every graph you should use the line test with is when you draw a line from top to bottom and if the line touches more then one dot or line on the graph it isnt not a function
.im sorry but where’s the picture
Answer:
blep
Step-by-step explanation:
Higher then the levels of ten and lower of the x-axis through the ten starting with negative ten to y axis 10
There are many polynomials that fit the bill,
f(x)=a(x-r1)(x-r2)(x-r3)(x-r4) where a is any real number not equal to zero.
A simple one is when a=1.
where r1,r2,r3,r4 are the roots of the 4th degree polynomial.
Also note that for a polynomial with *real* coefficients, complex roots *always* come in conjugages, i.e. in the form a±bi [±=+/-]
So a polynomial would be:
f(x)=(x-(-4-5i))(x-(-4+5i))(x--2)(x--2)
or, simplifying
f(x)=(x+4+5i)(x+4-5i)(x+2)^2
=x^4+12x^3+77x^2+196x+164 [if you decide to expand]
