Find the y-intercept of the parabola y = x2 + 6x.

Can somebody help?

Given:

The equation of the parabola is:

To find:

The y-intercept of the parabola.

Solution:

We have,

Putting in the given equation, we get

Therefore, the y-intercept of the parabola is 0. It means the y-intercept of the given parabola is at point (0,0).

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
