What are the domain and range of the exponential function below?

f(x) = 4x + 3

a. domain: all real numbers greater than 0
range: all real numbers greater than 0
b. domain: all real numbers
range: all real numbers greater than 3
c. domain: all real numbers
range: all real numbers greater than 0
d. domain: all real numbers greater than 0
range: all real numbers greater than 3

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
