Question

Determine the statement that best fits the formula shown:

y-x^2 = 1

a. y is not a function of x
b. y is a linear function of x
c. y is a quadratic function of x
d. y is a logarithmic function of x

Answer 1

since we have square term we can rule out linear function

Answer 2

i believe C because x^2 is quadratic

Answer 3

because you have to use the QUADRATIC formula to find the value of x, this is a quadratic function. this is an easy way to remember this.

Answer 4

For every x value there is only one y value, so it is a function, that rule out first choice
