Question

Writing Assignment: Your friend in another school has just sent you a

screenshot of a math problem and needs your help. IN WORDS, you must
describe how to solve the problem and you must include your solution.
Remember to use COMPLETE sentences. Include math vocabulary (coefficent,
variable, functions, etc) in your verbal description. Here is the problem:
Evaluate if x = 4.
f(x) = = - 3x + 8

Answer 1

Given that,

f(x) = -3x + 8

To find,

The value of f(x) at x = 4.

Solution,

We have,

f(x) = -3x + 8

We need to find the value of f(x) at x = 4

Pu x = 4 in f(x).

f(4) = -3(4) + 8

= -12 +8

= -4

So, f(4) is equal to -4.
