What is the value of the range of the function f(x)=2x^2-3x+8 for the domain value 3
Lelechka [254]
The domain is the same as the x value and the range is the same as the y value, so you just plug in the 3 to all the x's.

f(x) = 2 ({3})^{2}  - 3(3) + 8 \\ f(x) = 18 - 9 + 8 \\ f(x) = 17
the range of the function is 17

Choose the correct conic section to fit the equation. X=1/16y^2
arsen [322]

Hello from MrBillDoesMath!

Answer:

Parabola

Discussion:

The equation is x = (1/16) y^2. Multiply both sides by 16 to get

y^2 = 16x is a parabola that "opens to the right". (Looks like y = x^2 rotated clockwise 90 degrees)

Thank you,

MrB
