Which is the vertex of x^2 + 10x = - 17?
Dafna11 [192]

Answer:

(-5, -8)

Step-by-step explanation:

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

x^2 + 10x = - 17

x^2+10x+17=0

x^2+2*5x+25 - 8=0

(x+5)^2-8=0

h=-5, k= -8

vertex is (-5, -8)

What statement best describes the effect of replacing the function f(x)=2x-2 with the function g(x)=2x+3
madreJ [45]

You can easily see that

f(x) = g(x)-5

In fact, you have

g(x)-5 = 2x+3-5 = 2x-2 = f(x)

This kind of transformation, where you add a constant to change

f(x) \mapsto f(x)+k

result in a vertical translation, k units up if k>0, k units down if k

So, in this case, the graphs of f(x) and g(x) have the same shape, and they are vertically shifted 5 units apart, g(x) is higher and f(x) is lower.
