Question

HELP PLEASE been on this question for the past hour

Answer 1

Randy and Brandon are studying for their SAT. They come across a question where they need your help. The question reads, "How can key features be used to create a sketch of any polynomial function?"

Explain to Randy and Brandon, in complete sentences, what key features are necessary and how they can be used to create the sketch of a polynomial function.

Answer 2

cant remember anything about polynomials

Answer 3

at least a bump into it to help me remember....

Answer 4

hint the degree of the polynomial in one variable is the highest power of the variable. the number of zeros will be the places where the function crosses the x-axis. To do a basic sketch what is the value of y when x = 0 and the value of x when y = 0

Answer 5

and then first derivative will give the slope, second derivative general curvature up or down

Answer 6

mmmm im kinda confuse..

Answer 7

two key features you could use is, as @triciaal already pointed out, the intercepts
to get the x-intercept, you set y=0 and solve for "x"
that gives you where the graph TOUCHES or INTERCEPTS the x-axis

to get the y-intercept, you'd set x=0 and solve for "y"
that gives you where the graph TOUCHES or INTERCEPTS the y-axis

Answer 8

ohhhhhhhhh i see i see... i saw that, what jameswolf said confused me a lil

Answer 9

sorry

Answer 10

its fine, it made me think
