Question

Graph each pair of parametric equations.
x = 2t – 1
y = t2 + 5, -4 ≤ t ≤ 4

Answer 1

Try this, https://graphsketch.com/parametric.php is has setting for t

Answer 2

But use it to check only, so graph it yourself first! :)

Answer 3

I don't understand why it's not working.

Answer 4

x(t)=2t-1
y(t)=(t)^2+5

T range -4 to 4

Answer 5

You should get a parabola

Answer 6

Nothing shows up

Answer 7

You have to click on plot

Answer 8

I did.

Answer 9

Is it possible for you to screenshot what data you entered?

Answer 10

what are your xmin, xmax, ymin, ymax?

Answer 11

-17 to 17
and
-10.5 to 10.5

respectively

Answer 12

you should see a blue curve

Answer 13

Do you see the parabola?

Answer 14

this is what I got

https://graphsketch.com/parametric?mode=para&eqn1_color=1&eqn1_x=2t-1&eqn1_y=(t)%5E2%2B5&eqn2_color=2&eqn2_x=&eqn2_y=&eqn3_color=3&eqn3_x=&eqn3_y=&x_min=-17&x_max=17&y_min=-10.5&y_max=25&t_min=-4&t_max=4&x_tick=1&y_tick=1&x_label_freq=5&y_label_freq=5&do_grid=0&do_grid=1&bold_labeled_lines=0&bold_labeled_lines=1&line_width=4&image_w=850&image_h=525

Answer 15

Weird

Answer 16

Yeah same

Answer 17

I entered the same data, Jim

Answer 18

So strange. Maybe you need to refresh somehow.

Answer 19

I'll try that. Thank you both.

Answer 20

Np, take care
