So whats the question or you stating a statement.
3/4 and 75/100 are the correct answers
Scale factor is equal to 1/2, since the point went from 10 to 5
So?
-756*x +x =1 ?
-755 x = 1
x= -1/755
or
what two numbers when multiplied equal -756 but when added together equal 1?
numbers are x and y
x*y= -756
x+y=1
rearrange the 2nd eq
y=1-x
substitute
x(1-x)=-756
distribute
x-x^2=-756
solve for zero
x^2-x-756=0
factor/quadratic equation
Answer:
The function 
Step-by-step explanation:
The Range of any function is complete set of all possible resulting values of the dependent variable , after substituting the domain.
so, the function
has range
This includes - 4 .
Hence, the function is
.
