What is the effect on the graph of the function f(x) = 2x when f(x) is replaced with f(−5x)?

a) vertical stretching and reflection across the x-axis

b) vertical compression and reflection across the x-axis

c) horizontal compression and reflection across the y-axis

d) horizontal stretching and reflection across the y-axis

C)horizontal compression and reflection across the y-axis

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.

Please see the attached image below, to find more information about the graph

The original equation is:

f(x) = 2x

The new equation is:

f(-5x) = 2(-5x)

f(-5x) = -10*x

The answer is

C)horizontal compression and reflection across the y-axis

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

24 units
