Mathematics

AURORKA [14]3 years ago

<h3><u>Explanation</u></h3>
  • Meaning of f(a)

f(a) means the value of f(x) is ... when x = a. That means if we substitute x = 3, we would get f(3).

f(3) also means the value of f(x) is ... when x = 3.

f(x) can also be defined as y // f(x) = y

  • Find f(3) by graph.

You can find the value of f(x) at specific domain from the graph by looking at x = 3 then look up to where the point or where the graph passes. From the graph, when x = 3 as we look up and the graph passes y-coordinate at 1.

Therefore we can say that when x = 3, y = 1.

<h3><u>Answer</u></h3>

f(3) = 1

The numeric values for the function are given as follows:

a) f(-5) = 14.

b) f(0) = 10.

c) f(5/2) = 8.

d) f(5a) = -4a + 10.

e) f(5a - 15) = -4a + 22.

<h3>How to find the numeric value of a function?</h3>

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is given by:

f(x) = -0.8x + 10.

Hence the numeric values are given as follows:

  • f(-5) = -0.8(-5) + 10 = 14.
  • f(0) = -0.8(0) + 10 = 10.
  • f(5/2) = f(2.5) = -0.8(2.5) + 10 = 8.
  • f(5a) = -0.8(5a) + 10 = -4a + 10.
  • f(5a - 15) = -0.8(5a - 15) + 10 = -4a + 22.
