Answer:
by air pollution and also by the waste of garbage
The quadratic function when graphed out should look like either a 'U' or an 'n' (parabola). Quadratic functions have formulas which are typically in the form of: A(x^2)+Bx+C where A, B, C are numbers and if you plot them then as mentioned before you should get a parabola.

Step-by-step explanation:
Given
2x + 7y = 42
To find the x- intercept let y = 0 in the equation and solve for x
2x + 7(0) = 42, that is
2x = 42 ( divide both sides by 2 )
x = 21 ← x- intercept or (21, 0 )
To find the y- intercept let x = 0 in the equation and solve for y
2(0) + 7y = 42 , that is
7y = 42 ( divide both sides by 7 )
y = 6 ← y- intercept or (0, 6 )
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = - 3 and b = 2 (Center at </span></span> A(-3,2))
<span>
r = AP....P(2,-5)
r² = (AP)²
r² = (2+3)² +(-5-2)² = 25+49=74
an equation of the circle that satisfies the stated conditions.
Center at </span> A(-3,2), passing through P(2, −5) is : (x+3)² +(y-2)² = 74
