Answer:
Domain : (-∞,∞) Range : (-∞,∞)
Step-by-step explanation:
Given:
f(x) = 3x+5
To find: Domain and Range of f(x)
Domain is the set of values that x can take.
Range is the set of values of y corresponding to the values of x in the domain.
Here x can take any value and the domain is the set of real numbers i.e (-∞,∞).
f(x) = 3x + 5
The graph of f(x) is a straight line that extends from -∞ to +∞ and hence the range is (-∞,∞).
Answer:
x=1.47
Step-by-step explanation:
15(x-1)+4(x+3)=2(x+9)+4
15x-15+4x+12=2x+18+4
19x-3=2x+22
17x=25
x=25/17
x=1.47
