Answer:
x^2 - 4x - 1
Step-by-step explanation:

In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.

<em>Multiply -4 and -3 in the function above.</em>

<em>Add 3 on both sides of the equation.</em>


<em>Add 2y on both sides of the equation.</em>


<em>Divide both sides of the equation by -3.</em>


Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.
Answer:
f(-3) = -5

Answer:
60 cm is the answer
Step-by-step explanation:
Circumference = 2(pi)r
Area = (pi)r^2
r = 5
5 * 2 = 10
Circumference = 10π
5 * 5 = 25
Area = 25π
Using 3.14 as pi substitute:
5 * 3.14 = 15.7
15.7 * 2 = 31.4
Circumference = 31.4
5 * 5 = 25
25 * 3.14 = 78.5
Area = 78.5
