Which statement is true about the y-intercept of a quadratic function?
Dafna11 [192]

Answer:

A.

Step-by-step explanation:

A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.

Choice B contradicts the previous statement.

Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.

Choice D is wrong because the y-intercept is where x = 0.

I hope this helps!

The price of silver went from $26.40 a troy ounce down to $17.16 a troy ounce during the past 6 months. This represents a decrea
const2013 [10]

There is decrease of 35% in the price of silver in the past 6 months.

<u> Solution: </u>

Given that  

Price of silver went from $26.40 a troy ounce down to $17.16 a troy ounce during past 6 months need to represent this decrease in percentage  

Price of silver before 6 months = initial price = $26.40

Price of silver now = current price = $17.16

Difference in price in 6 months = 26.40 – 17.16 = $9.24

\text { Decrease in percentage }=\frac{\text { Diffrence in } 6 \text { months }}{\text { Initial price }} \times 100

\begin{array}{l}{=\frac{9.24}{26.4} \times 100} \\\\ {=0.35 \times 100=35 \%}\end{array}

Hence there is decrease of 35% in the price of silver in the past 6 months.
