What value of x makes f(x) = -2 if f(x) = 3.4x - 7.1

a. -13.9 b. -1.5

c. 1.5 d. 2.8

Option C

For x = 1.5 we get f(x) = -2

Solution:

Given function is:

We have to find the value of "x" so that f(x) = -2

Substitute f(x) = -2 in given function

Solve for "x" by moving the constants to one side and variables to other side

For x = 1.5 we get f(x) = -2

We can verify by substituting x = 1.5 in given function

Thus for x = 1.5 we get f(x) = -2

answer: about 22.67
