Question

two less than the product of a number and three Evaluate when f = 4.5. Evaluating an Algebraic Expression Write and evaluate the expression shown on the left. Then, check all that apply. Write the expression as 2 – 3f. Write the expression as 3f – 2. Write the expression as 2f – 3. The value when f = 4.5 is 6.75. The value when f = 4.5 is 6. The value when f = 4.5 is 11.5.

Answer 1

Write the expression as 3f – 2.

The value when f = 4.5 is 11.5.

Explanation:

Let f be the number.

Then the product of the number and three is 3f.

Two less than 3f is 3f -2.

=====

f(4.5) = 3×4.5 - 2

f(4.5) = 13.5 - 2

f(4.5) = 11.5
