the table below represents a linear function f(x) and the equation represents a function g(x):

x f(x)
−1 −5
0 −1
1 3
g(x)

g(x) = 4x + 3

part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

part b: which function has a greater y-intercept? justify your answer. (4 points)

OK, so we know that every linear function can be written as y=mx+b

So substituting -5 as y and -1 as x we get -5=-m+b

Then substituting -1 as y and 0 as x we get -1=0*m+b=b

solving we get b=-1

so we substitute b=-1 in -5=-m+b and we get -5=-m-1 or -m=-4 which is m=4

so f(x)=4x-1, and the slope is the m in y=mx+b which is 4.

Part B

y intercept is when x=0

Substituting y=0 in f(x)=4x-1 and we get -1

Substituting y=0 in g(x)=4x+3 and we get 3

So y-intercept of g(x) is greater than y-intercept of f(x)

Hope this helps.

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
