Consider the function y=x^2+5x-2 . What would happen to the graph if (x -1) was substituted in place of the x?
Ilia_Sergeevich [38]

Answer:

B.

Step-by-step explanation:

f(x - c) shift the function <em>c</em> units to the right.

In this case, if (x - 1) was substituted in place of the x, the graph would shift 1 unit to the right.

If you want to graph the new function and know the graph of the previous one, this relationship avoids you the substitution of (x - 1) into the function and expansion of the expression to obtain a new quadratic formula.

Find the solutions of the quadratic equation 3x^2 – 2x +4= 0.
Sergeeva-Olga [200]

Answer:

C. x =(1±i√11)/3

Step-by-step explanation:

Use the quadratic formula to find the solutions.

(−b±√b²−4(ac))/2a

Substitute the values a=3, b=−2, and c=4 into the quadratic formula and solve for x.

2±√(−2)²−4⋅(3⋅4)2⋅3

Simplify.

x=(1±i√11)3
