  no

Step-by-step explanation:

An equation representing a proportional relationship looks like ...

  y = kx

where k is the constant of proportionality. A notable feature of this equation is that its y-intercept is zero.

Your expression has a y-intercept of +4, so does not represent a proportion.

Additional comment

Strictly speaking, a proportion is a statement of equality of two ratios. An expression cannot be a proportion. We interpreted your question to be ...

  does y = 3x+4 express a proportional relationship?

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
