Substitute the given into the function
f(-4) = |7(-4) - 3|
now solve
f(-4) = |-28 - 3|
f(-4) = | -31|
the absolute value of |-31| is 31
so,
f(-4) = 31
Hope this helps :)
Answer:0.5
Step-by-step explanation: If you flip the numbers and the continue to multiply them across and then divide them after you should get 0.5
Answer:
See below
Step-by-step explanation:

The +k part of the function takes the original function and translates it straight up k units. It's as simple as that. If your function is the line f(x) = 3x, then the function f(x) = 3x + 4 moves that first function up 4 units.
Given a point in coordinates form

, one can compute the cartesian form like this:

We have:

We get the cartesian form then:
