Aparabola is represented by the equation y = x2 + 6x − 17. the x-intercepts of the parabola . the y-intercept of the parabola . (if necessary, round your answers to the nearest hundredth.)

2.8, 8.8, and -17 respectively.

Step-by-step explanation:

We need to find roots of the equation.

x-intercepts : ≈

y- intercepts :

Step-by-step explanation:

To find the x-intercept(s), substitute in  0 for y and solve for x.

thus

Using quadratic formula for finding value of x.

                            ±

thus we get,

   x-intercepts :   ≈

Now for y-intercept(s), substitute in 0 for x and solve for y.

thus

we get,

                  y- intercepts :

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
