Question

In the function

f(x) = 5x + 12
how does an increase of 1 in the independent variable x affect
f(x)?

f(x) will have an increase of 5
f(x) will have a decrease of 17
f(x) will have an increase of 5x + 5
f(x) will have a decrease of 5

Answer 1

increase by 5

Answer 2

if x = 2 you get
\[5\times 2+12=10+12=22\] if x = 3 you get
\[5\times 3+12=15+12=27\]

x increases by 1, y increases by 5
