Answer:
the parabola can be written as:
f(x) = y = a*x^2 + b*x + c
first step.
find the vertex at:
x = -b/2a
the vertex will be the point (-b/2a, f(-b/2a))
now, if a is positive, then the arms of the parabola go up, if a is negative, the arms of the parabola go down.
The next step is to see if we have real roots by using the Bhaskara's equation:

Now, draw the vertex, after that draw the values of the roots in the x-axis, and now conect the points with the general draw of the parabola.
If you do not have any real roots, you can feed into the parabola some different values of x around the vertex
for example at:
x = (-b/2a) + 1 and x = (-b/2a) - 1
those two values should give the same value of y, and now you can connect the vertex with those two points.
If you want a more exact drawing, you can add more points (like x = (-b/2a) + 3 and x = (-b/2a) - 3) and connect them, as more points you add, the best sketch you will have.

I can’t see it can you take a clear picture
Step-by-step explanation:
Answer:2.5×10^-5. (And i think u meant in Scientific Notation)
Step-by-step explanation//Give thanks(and or Brainliest) if helpful (≧▽≦)//
First write the equation 8 + 12 > x because according to the triangle property, the sum of any 2 sides have to be greater than the third side. This means that the difference of any two sides should be smaller than the third side.
So, the answer would be 4 < x < 20.
Answer: Eleven Fourths xEight Ninths.
Step-by-step explanation: To get the mixed number Eleven Fourths, you have to multiply 4x2 (4 as the denominator and 2 as the whole number) to get 8, and add 3 (numerator) to get 11, and then put 4 over it as the original denominator to get 11/4. Then, just plug back in the numbers: 11/4 x 8/9 (Eleven-Fourths times Eight-Ninths)
