Question

n the function
f(x) = 5x - 11

how does a decrease of 1 in the independent variable x affect
f(x)?

Answer 1

say x = 1

f(x) = 5x - 11

f(1) = 5(1) - 11

f(1) = 5 - 11

f(1) = -6

So when x = 1, f(x) = -6

Answer 2

f(x) will have a decrease of 5
f(x) will have an increase of 5
f(x) will have an increase of 16
f(x) will have a decrease of 5x - 5
are the choices

Answer 3

now say x = 0 (x decreases by 1)

f(x) = 5x - 11

f(0) = 5(0) - 11

f(0) = 0 - 11

f(0) = -11

Now when x = 0, f(x) = -11

Answer 4

you have these two facts

x = 1, f(x) = -6

and

x = 0, f(x) = -11

Answer 5

i dont get it

Answer 6

what does that have to do with the problem

Answer 7

going from f(x) = -6 to f(x) = -11 has f(x) decreasing by _____

Answer 8

5

Answer 9

so f(x) decreases by 5 when x decreases by 1

Answer 10

which is exactly what the slope is saying

Answer 11

is f(x) will have a decrease of 5 the answer

Answer 12

yes

Answer 13

you sure

Answer 14

yes

Answer 15

thanks very much
