Answer 2

did you determine what the functions f and g are in standard form?

Answer 3

I'm unable to write the points in standard form.

Answer 4

Answer 5

for the first function, f, you can use knowledge that parabolas are symmetric about the vertex and derive the coefficients that way (or just graph it). i.e., you know the vertex is at (-1, 4), you also know (-2, 3) is a point. that means you also know the y-coordinate for the point where x = 0 (based on symmetry alone). for the second function you may expand it out and determine the y-intercept.

Answer 6

alternatively you can always plug in x = 0 in g(x) to determine its y-intercept. but i see the word 'graph' a lot in your problem, so i'm assuming you ought to graph it to get an idea

Answer 7

that looks like an accurate representation of f(x), nice.

Answer 8

do you need more help?

Answer 9

yes
