Question

Given f(x)=−3.7+1, what is the value of f(−9)?

a) f(−9)=−12.7
b) f(−9)=7.3
c) f(−9)=−2.7
d) f(−9)=2.3

Answer 1

For the function f(x)=−3.7+1, the value f(−9) is constant and equals −2.7, matching choice c (f(−9)=−2.7). There seems to be a mistake as the function should depend on x for the value to change with different inputs of x.

Step-by-step explanation:

The value of f(−9) for the function f(x)=−3.7x+1 can be found by substituting x with -9. The function represents a linear relationship between x and f(x). When you substitute -9 into the function, it becomes f(−9)=−3.7*(-9)+1, which simplifies to f(−9)=33.3+1=34.3. However, none of the provided options match this result. It appears there might be an error in the function provided or in the options available. If f(x) is truly meant to be f(x)=−3.7+1, then f(−9) is not dependent on x and is thus a constant value of f(−9)=−3.7+1=−2.7.
