Answer: The required values are
f(-2) = 120, f(0) = 64 and f(1) = 84.
Step-by-step explanation: We are given the following function f(x) :
We are to find the values of the following :
To find the values of the function at the given points, we need to substitute the corresponding values of x in equation (i).
Substituting x = -2 in equation (i), we get
Substituting x = 0 in equation (i), we get
Substituting x = 1 in equation (i), we get
Thus, the required values are
f(-2) = 120, f(0) = 64 and f(1) = 84.

Answer:
The solution is (2,6)
Step-by-step explanation:
Let
x-----> the number of hours to change a fuel injection unit
y-----> the number of hours to change a transmission
we know that
5x+10y=70 -----> equation A
8x+8y=64 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2,6)
see the attached figure
