Mathematics

Answer: Option C.

Step-by-step explanation:

A function goes trough the x-axis when f(x) = 0 for some value of x.

For example, when we say that a quadratic function has no real zeros, this means that the determinant is less than zero, so the roots of the equation:

a*x^2 + b*x + c = 0

are complex roots, this means that for the function:

f(x) = y = a*x^2 + b*x + c

there is not a real number x such f(x) = 0

So the correct option is C.

Your cell phone plan costs $44.99 per month. You also pay 20% in taxes and fees. What is your bill after taxes and fees?
katen-ka-za [31]
So the total bill will be 44.99 + 20% of 44.99 or the total bill (x) will equal 44.99 + .20 × 44.99

x = 44.99 + (.20)44.99
x = 44.99 + 9.00
x = $53.99

*note- .20(44.99) = 8.998 which rounds to $9.00
