F(x) = 2x² - 8x - 10.
This is a parabola open upward (since a>0) with an axis of symmetry = -b/2a:
a) axis of symmetry: x = -(-8)/(2*2) = 8/4 = 2. Then x = 2, which is the x component of the vertex
b) for x = 2, f(x) = f(2) = - 18 (component of y of the vertex)
c) VERTEX(2, - 18)
d) DISCRIMINENT: b² - 4.a.c = 64 - 4*2*(-10) = 144

Answer:
To do this question, we must first convert Pi to a decimal form, as shown below:
Pi = 3.14
So then our equation becomes:
3.14 x 36 - 16
We still need to remember PEMDAS.
Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
So according to PEMDAS, we need to do 3.14 x 36, which equals 113.04
Now we have to do:
113.04 - 16 = 97.04
Our answer is 97.04
