To do this, we multiply

3/ \sqrt{7}* \sqrt{7}/ \sqrt{7}

We can do this be square root 7/square root 7 equals one.  The result of this is:

galina1969 [7]

| E - G | = EG

| -2 - G | = 10

-2 - G = 10                 -2 - G = -10

   - G = 12                      - G = -8

     G = -12                       G = 8

Answer: -12 or 8

Evaluate the function. f(x) = 3x² – x Find f(10)​
kirill [66]

Answer:

<em>f(10)=290</em>

Step-by-step explanation:

<u>Function Evaluation</u>

Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.

We are given the function:

f(x)=3x^2-x

It's required to find f(10). We replace the x for 10:

f(10)=3*10^2-10

Operating:

f(10)=3*100-10

f(10)=300-10

f(10)=290

Thus, f(10)=290
