What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(3x)? A) stretched vertically B) compressed vertically C) stretched horizontally D) compressed horizontally

if x decreases by 4 then y increases by 10

step-by-step explanation:

where r the answers

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

step-by-step explanation: hi!
