find the indicated outputs for f(x)=3x^2-5x
I get
f(0)=0
f(-1) = 1
f(2) =8)
am I doing this right if not could you explain where I am wrong.
yes, no ...3(-1)62-5(-1)=3+5=2
and finally, no. Rework that. What is 3*4-10?
This would be 2 but how can f(2)=2
yes, f(2)=2. 3*2^2-5*2=12-10=2
The given function is f(x) = 3x^2 - 5x. To find the indicated outputs, you need to substitute the given values into the function and calculate the result. Let's check your calculations:
f(0) = 3(0)^2 - 5(0)
= 0 - 0
= 0
Your calculation for f(0) is correct.
f(-1) = 3(-1)^2 - 5(-1)
= 3(1) + 5
= 3 + 5
= 8
Your calculation for f(-1) is incorrect. The correct calculation is f(-1) = 8, not f(-1) = 1.
f(2) = 3(2)^2 - 5(2)
= 3(4) - 10
= 12 - 10
= 2
Your calculation for f(2) is incorrect. The correct calculation is f(2) = 2, not f(2) = 8.
To summarize, you calculated f(0) correctly as 0, but made errors in calculating f(-1) and f(2). The correct values are f(-1) = 8 and f(2) = 2.
