Given f(x) = 3x^2 − x + 5, find f(1.6)

Answer 1

Hello, thank you for taking the time to post your question!

For this expression you would just plug in x = 1.6 into the function for the value of x and then evaluate following the order of operations

f(1.6) = 3(1.6)^2 – 1.6 + 5

=3(2.56) – 1.6 + 5

=7.68 – 1.6 + 5

=6.08 + 5

=11.08

Hopefully that gets you moving in the right direction! Feel free to reach out for a lesson if you have any questions beyond that! :)

Answer 2

Take the time and evaluate the given mathematical problem.

Given f(x) = 3x^2 - x + 5, find f(1.6)

List the mathematical facts:

The function f(x) = 3x^2 - x + 5.

The value x = 1.6

Calculate the value of the function f(x) where x = 1.6

f(x) = 3x^2 - x + 5

Use the Step By Step Method

We need to Substitute x = 1.6 into F(x) equation: 3x^2 - x + 5

So, f(1.6) = 3 times (1.6)^2 - 1.6 + 5

Exponent Power of 2 = multiply the (1.6) twice

Calculate (1.6)^2 = 1.6 x 1.6 = 2.56

Multiply 3 x (2.56)

3 times (2.56) = 7.68

Subtract 7.68 - 1.6

7.68 - 1.6 = 6.08

Add 6.08 + 5

6.08 + 5 = 11.08

Final Answer: The value of the function = 11.08

Therefore, f(1.6) = 11.08

I hope the mathematical calculations (step by step approach) was helpful. Please let me know if you require any more assistance. If anyone in my neighborhood is interested in setting up an in-person math tutoring session. I look forward to hearing from them. Have an amazing day. Doris H.

Answer 3

F(1.6)=3*(1.6)²-1.6-5

First substitute in x=1.6 to the function

Next work with the exponents first

3*(2.56)-1.6+5

Next multiply 3 and 2.56

7.68-1.6+5

Finally carry out subtract on the left first then add 5 per PEMDAS

So the answer will equal 11.08 as the y value of the function

Any questions please let me know.

Answer 4

We substitute in directly and then solve with PEMDAS

Exponent: f(1.6) = 3*(1.6)^2 - 1.6 + 5

Multiplication: f(1.6) = 3*(2.56) - 1.6 + 5

Addition/Subtraction: f(1.6) = 7.68 - 1.6 + 5 = 11.08
