Given f(x) =2x+1 graph the transformation 2f(x)

Question

transformtiontransformation

Answer 1

2f(x) = 2(2x+1) = 4x+2

f(x) is a straight line with slope = 2 and y intercept = 1

2f(x) is a straight line with slope = 4 and y intercept = 2

2f(x) is twice as steep and intersects the y-axis at a value twice where f(x) intersects the y-axis
