<span>The parabola intercepts the x-axis happen when? Well, it's when "y" = 0. So you want to solve for x, 0 = 2x^2 + 2x -4</span>
The answer is A
For a function, all you really need to do is plug in any “in” number to the equation to find the “out” number
For example: plugging in 5 into equation 1 would be:
f(5) = 9(5) + 4 = 49
If you keep doing this to each of the other “in” values, you would get the “out” values

Step-by-step explanation:
Answer:
12.56 square yards
Step-by-step explanation:
From the question we are given;
the diameter of a circular patio as 4 yards
but, radius = diameter/2
= 2 yards
We are required to calculate the area of the patio
Area of a circle = πr²
Therefore;
Area= 3.14 ×2²
=12.56 square yards
Thus, the area of the patio is 12.56 square yards
