Answer:
- both are linear functions with a y-intercept of 3 and domain of all real numbers
- f(x) has positive slope, so a range of all real numbers
- g(x) has zero slope, so a range of only the value 3
Step-by-step explanation:
Both functions are shown in the attached graph. Both are linear functions with a y-intercept of 3. Both have a domain of all real numbers.
Function A has a positive slope, so has a range of all real numbers.
Function B has a zero slope, so its range is the single number y = 3.
Domain is all the possible inputs of an equation. In this example, the only concern is the x + 5 because the denominator cannot equal 0 because we can't divided by 0. So we set x + 5 equal to zero and solve for x.
x + 5 = 0
x = -5
The restriction is that x cannot equal -5.

Step-by-step explanation:
surface : 4×pi×R^2
R1 = 5x
R2 =8x
4piR1^2 / 4piR2^2 = R1^2/R2^2 = 5x^2/8x^2 = 25x^2/64x^2 = 25/64
