Question

if a linear function is a straight line on a graph, does that mean it has no maximum?

Answer 1

hey you helped me earlier

Answer 2

hey

Answer 3

depends on your domain.

Answer 4

how do i find the domaiin

Answer 5

i know xis greater than or = to 0

Answer 6

if the domain is from -infinity to +infinity, then the straight line has no maxima or minima.

Answer 7

then your boundary values are where the line will have a maxima or minima

Answer 8

so plug in x = 0 in your equation and see what the output is. That should be your minima.

Answer 9

you dont have a maxima because there is no boundary to infinity.

Answer 10

when i solved for the max, i used -b/2a and came up with x=2500

Answer 11

then i plugged that into p(2500)= -.01(2500)^2+50(2500)+30000
to come up with 92500

Answer 12

when i plugged in 0 into the equation, i got 30,000

Answer 13

your equation is quadratic. it is not a straight line.

Answer 14

your question was to do with straight lines.

Answer 15

how did you kknow it is a quadratic

Answer 16

because p(x) = -.01x^2 +50x+30000

Answer 17

there is an x^2 term. so it is quadratic---> not a straight line.

Answer 18

then the question isAnnual profit in thousands of dollars is given by the function, P(x) = -.01x2 + 50x + 30,000, where x is the number of items sold, x ≥ 0.
then graph the profit function over its given domain

Answer 19

use the 5 values to construct the graph
1,2,3,4,5

Answer 20

you already asked me this question. I thought i had replied earlier

Answer 21

yes but the graph

Answer 22

i know the rest

Answer 23

how would i graph this?

Answer 24

would y then be
1
30049.99
2 30099.96
3 30149.91
4 30199.84
5 30249.75

Answer 25

P(x)
