Answer: III. y = x^2 - 2x - 48

The y intercept are the points on the graph where the curve hits the y-axis, so it’s the point where x=0
With the equation y=x^2 - 2x - 48 we can easily plug in 0 for x and see that the when x is zero, y is -48.

The area of square abcd is 7cm^2 <br><br>show that x^2+4x=3
AveGali [126]

Answer:

see explanation

Step-by-step explanation:

The area (A) of the square = s² ( s is the measure of the side )

Here s = x + 2 and A = 7 , thus

(x + 2)² = 7 ← expand left side using FOIL

x² + 4x + 4 = 7 ( subtract 4 from both sides )

x² + 4x = 3 ← as required
