Consider the quadratic function f(x)=2x^2-8x-10

Slav-nsk [51]

Answer:

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

Hope this helps! :)

Verizon [17]

Answer: ⇒ The finance charge = $77

Given: The cost price of DVD player= $295

Since, Tim agreed to pay $31 per month for 12 months .

Therefore, the total amount paid by Tim= $31\times12=\$372$

The finance charge = $\text{Amount paid by Tim - Cost price of DVD}$

⇒ The finance charge = $\$372-\ $295$

⇒ The finance charge =$77
