Mrs. Beachy would drive 53mph. How I did it:954÷18(18 can't go into 9.... 95?)Yes, 5 times.954÷18= 5 -(Okay... 95-90 is 5, drop the four... 54?)18x3 is 54!954÷18=54! So the answer is 54mph (Right? I am sure I did that right...)
        
             
        
        
        
Therefore, f(x) = 2x + 3 is your derivative function, and you need to find the original curve. So find the antiderivative using the given conditions... 
∫f(x) = ∫2x + 3 dx 
F(x) = x^2 + 3x + C 
2 = (1)^2 + 3(1) + C 
2 = 4 + C 
C= -2 
Therefore, the curve is F(x) = x^2 + 3x - 2 
Proof: The derivative is the slope at every (x, y) point. The derivative of F(x) comes out to be 2x + 3, so we have found the curve. Plug in x = 1, and y = 2, so the conditions have been met.

Answer:
 <em>y = (x - 4)² - 4 </em>
Step-by-step explanation:
y = x² - 8x + 12 
y = ( x² - 2(4)x + 4² ) - 4² + 12 
<em>y = (x - 4)² - 4</em>
