Question

What is the equation of the graph below?


y = –2(x – 3)2 + 1
y = 2(x + 3)2 + 1
y = –2(x + 3)2 + 1
y = 2(x – 3)2 + 1

Answer 1

the curve is concave down so the coefficient of x^2 is negative...

so that eliminates answers 2 and 4

the roots are shown on the positive section of the x-axis

the equation that has positive roots is the 1st
