juin [17]
Find ing the common denominator would make it 10.
for 1/2 to get to 10 you have to multiply by 5
1/2x5= 5/10
then you have to convert 2/5 to get the denominator to be 10
so you multiply 2/5 by 2
2/5x2= 4/10

What is the domain of f(x)=-5x+4
ANTONII [103]

Answer:

f(x) = -5x + 4

Domain refers to the values of x that would result to  a defined value of y. Since the given f(x) is a linear function, then all the values of x would give a corresponding value of y. So, the domain of f(x)=-5x+4 are all real numbers.

Or, plot the given equation to check.

The graph of f(x)=-5x+4 is shown below.

Since the graph is a straight line and can be extended continuously on both ends,  this indicates that every values of x, there is a corresponding value of y.

Hence, the domain of the given function are all real numbers.Step-by-step explanation:
