Answer:
f (x) = 2.3x grows the value of x at faster rate
The y-intercept coordinate is at the point (0, 17)
<h3>Properties of functions</h3>
Given the following function expressed as:
- The vertex of the function (h, k) is (2, 5) while the axis of symmetry is at x = 2
- Domain are the input values for which the function exist. According to the function, the domain and range exists on all real values
The x-intercept is the point where y = 0
Hence the x-intercept is (43/9, 0)
The y-intercept is the point where x = 0
The y-intercept coordinate is at the point (0, 17)

Answer:
k=20
Step-by-step explanation:
The constant of proportionality, k, measures the constant value of the ratio between two proportional quantities, being y and x in this case. Essentially, y/x will always equal 20, the constant of proportionality.
It’s the first one I believe.
