Did i do this right plz help

No, the first one you did get correct but the second, third and fourth are wrong here is you correct answer.
F(x) = 4x - x to the second power
So you substitute x for the numbers under x.
The second answer under f(x) is wrong it’s suppose to be...
F(x) = 4(0) - 0 to the second power the answer is 0.
The third answer under f(x) is also wrong the answer is...
F(x) = 4(-1) - -1 to the second power the answer is -3.
Looking back I see that under x the number 2 in f(x) is wrong also.
The answer Is f(x) = 4(2) - 2 to the second power equals 4.

4.2 Write 1764 as a product of prime factors show your steps​
Deffense [45]

Step-by-step explanation

first you have 1764 so you need to reduce it so you can keep on going through the line so I divided 1764 by 2 and I got 882. 2 is a prime number so I don't have to worry about it anymore. now I reduce 882 and get 2 and 441. 2 is prime so we don't need to worry about it anymore. now since we can't divide 441 by 2 we will use the next number 3. 441 divided by 3 is 147. 3 is prime so we don't need to worry about it anymore. 147 can't be divided by 2 so we will try 3 again and that works so 147 divided by 3 is 49. 3 is prime so we don't have to worry about it anymore. now we have 49 and 49 is a normal multiplication fact so we know that 49 divided by 7 is 7. and seven is prime so now you have have all the prime factors of 1764
