A curve is described by the following parametric equations: <br> x = 4-t<br> y = t^2 -2

marta [7]

Answer:

Step-by-step explanation:

Given

$x=4-t$

and $y=t^2-2\quad \ldots(i)$

So, $t=4-x$

Substitute the value of $t$ in $(i)$

$y=(4-x)^2-2$

$y+2=(4-x)^2$

So it represent a parabola shown in the figure

Give the function for f(x)-5|x+1|+3 for what values of x is f(x)=-12

Lyrx [107]

I’m not sure whether there is a typo in the function but I might have the answer.

If f(x) = 5(x+1)+3 = -12 then you can solve for x.

5(x+1)+3 = -12
5x + 5 + 3 = -12 << expand the brackets
5x + 5 = - 15 << minus 3
x + 1 = -3 << divide everything by 5
x = -4 << minus 1

I don’t know if this helps x Sorry
