Answer:
6 units
Step-by-step explanation:
Given
f(x) = 3[tex](7)^{x}[/tex]
To find the y- intercept let x = 0 , that is
y = 3[tex](7)^{0}[/tex] [ note [tex]7^{0}[/tex] = 1 ] , then
y- intercept = 3 × 1 = 3
The y- intercept of the line is - 3
Distance between 2 y- intercepts is
| 3 - (- 3) | = | 3 + 3 | = | 6 | = 6 units
