graph f(x) = x2 + 2x - 3, (use desmos) label the function’s x-intercepts, y-intercept and vertex with their coordinates. also, draw in and label the axis of symmetry.

  see attached

Step-by-step explanation:

It's almost easier for you to do this than it is to post a question on .

All you need to do is type the relevant expressions. Once you have Desmos show you the vertex, writing the x= equation for that is all that is required to draw it.

1/5

step-by-step explanation:

the dice has 6 sides and there is only one 5 in a dice.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
