What is the domain and range of the given parabola: y=6(x-4) 2 -1?

Domain: all real numbers Range: y≥-1

Domain: x≥-1 Range: all real numbers

Domain: all real numbers Range: y ≤-1

Domain: x ≤-1 Range: all real numbers

Does the following quadratic equation have a maximum or minimum value? How can you tell? y=x ²+2x-3

Minimum value, because the a value is positive

Maximum value, because the b value is positive

Maximum value, because the a value is positive

Minimum value, because the c value is negative

What steps transform the graph y = x 2 to y = -1/2(x-4) 2 + 1?

Reflected across x-axis, compressed by 1/2, shifted 4 units right and 1 unit up

Compressed by 1/2, shifted 4 units right and 1 unit up

Reflected across x-axis, stretched by 1/2, shifted 4 units left and 1 unit up

Stretched by 1/2, shifted 4 units right and 1 unit down

Which list orders the quadratic functions from narrowest to widest?

y = 4x 2 y = 2x 2 - 2 y = x 2 y = 0.5 x 2

y = x 2 y = 4x 2 y = 2x 2 - 2 y = 0.5 x 2

y = 0.5 x 2 y = x 2 y = 2x 2 - 2 y = 4x 2

y = 2x 2 - 2 y = 4x 2 y = 0.5x 2 y = x 2

What is this formula?

This is the speed of light formula.

This is the zero product property.

Your teacher gives you an equation in vertex form and wants you to convert it to standard form. Which one of the following describes the steps in the correct order?

1- Square the expression in parentheses. 2- Distribute the "a" value. 3- Combine like terms.

1- Distribute the "a" value. 2- Square the expression in parentheses. 3- Combine like terms.

1- Sketch the graph on the coordinate plane. 2- Identify 2 ordered pairs. 3- Use STAT-EDIT and STAT>CALC-Option 4 (LinReg)

1- Square the expression in parentheses. 2- Combine Like Terms. 3- Distribute the "a" value.
