<u>Answer:</u>

The value of f(3) when f(x) = x^2 - 3x - 1 is equal to -1

<u>Solution:</u>

The function that is mentioned to us in the question is

f(x)=x^{2}-3 x-1

We are asked to find the value of f(3)

The value of f(3) can be found by substituting 3 in place of “x” in the given function f(x)

<u><em>Finding the value of f(3):</em></u>

Now, for f(3), we substitute x= 3 in the above function,

f(3)=(3)^{2}-3(3)-1

f(3) = 9 - 9 - 1

f(3) = -1

Thus the value of f(3) when f(x) = x^2 - 3x - 1 is equal to -1

Solve for x.
Daniel [21]

Answer:

x=-\frac{9}{4} \\ or \:\\x = -2\frac{1}{4}

Step-by-step explanation:

-2 (x + 1/4)+1=5\\\\-2\left(x+\frac{1}{4}\right)+1=5\\\\\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}\\\\-2\left(x+\frac{1}{4}\right)+1-1=5-1\\\\Simplify\\-2\left(x+\frac{1}{4}\right)=4\\\\\mathrm{Divide\:both\:sides\:by\:}-2\\\frac{-2\left(x+\frac{1}{4}\right)}{-2}=\frac{4}{-2}\\\\Simplify\\x+\frac{1}{4}=-2\\\\\mathrm{Subtract\:}\frac{1}{4}\mathrm{\:from\:both\:sides}\\\\x+\frac{1}{4}-\frac{1}{4}=-2-\frac{1}{4}\\\\Simplify\\x=-\frac{9}{4}\\\\x = -2\frac{1}{4}
