Answer:

None

Step-by-step explanation:

We are given that a graph $h(x)=-3x^2$

We have to find that which pair lie on the given graph.

In order to find the value of ordered pair which lies on the given graph by substituting the value of x=1

If we get h(x)=-4 or -2 or 4 corresponding to x=1 then that pair will be answer.

Substitute x=1 then we get

$h(x)=-3(1)^2=-3$

The order pair is (1,-3).

Given options do not match with order pair (1,-3).

Hence, answer is none of the above.

given, y= -2x^2;

so, when x=1, y= -2((1)^2)= -2

so pair which lie on graph is (x,y) is (1,-2)

Write an equation in slope intercept form to model the situation.

Answer:

$y=-\frac{1}{2}x + 10$

Step-by-step explanation:

Slope intercept form is a way of modeling a quadratic equation, where the coefficient of the term ( $x$ ) is the slope (change) of the line, and the constant is the y-intercept. In essence;( $y=mx+b$ ), where ( $m$ ) is the slope and ( $b$ ) is the y-intercept.

The slope of the given line is ( $-\frac{1}{2}$ ) because, this is the rate at which the candle burns, therefore, it is the change in the line. The change is ( $\frac{1}{2}$ ) because this is the rate of burning, the slope is also negative since the height is decreasing. ( $10$ ) is the y-intercept because it is the starting height of the candle. One will take the time since the start of burning the candle, multiply it by the slope, and add it to the y-intercept to find the current height of the candle. Therefore, the equation is ( $y=-\frac{1}{2}x + 10$ ), where the output ( $y$ ) is the current height of the candle, and the input ( $x$ ) is the time at which the measruement was taken.
