Answer:
f(1) = 2
Step-by-step explanation:
<u>Step 1: Identify the function</u>
f(x) = x^2 + 2x^2 - x - 1
<u>Step 2: Simplify the function</u>
f(x) = 3x^2 - x - 1
<u>Step 3: Set x to 1 in the function</u>
f(1) = 3(1)^2 - (1) - 1
f(1) = 3*1 - 1 - 1
f(1) = 3 - 1 - 1
f(1) = 2
Answer: f(1) = 2

Answer:
A.
Step-by-step explanation:
first solve the actual inequality leaving you with x<=5
then to graph it find 5 on the number line and it must be an open dot and a line pointing to less than 5.
Answer: yes it would be C because deconstructed, it’s z + z + 6 which is the same as the original statement
