7 and anuber times a number
Answer:
![\sqrt{ {28x}^{2} - 6x }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7B28x%7D%5E%7B2%7D%20-%206x%20%7D%20)
Step-by-step explanation:
You would substitute "2x" for every "x" in the function in the same way you would substitute any other number.
So if f(x)=Sqrt[7x²-3x], then: f(2x)=Sqrt[7(2x)²-3(2x)]
=Sqrt[7(4x²)-3(2x)]
=Sqrt[28x²-6x]
77 - (-145) = 77 + 145 = 222
