The graph of the function g(x) = x2 + 3x - 4 is shifted 5 units to the left. Plot the zeros of the new function on the provided
jarptica [38.1K]
Horizontal translations
 Suppose that h> 0
 To graph y = f (x + h), move the graph of h units to the left.
 We have then:
 g (x + 5) = (x + 5) 2 + 3 (x + 5) - 4
 Rewriting we have:
 f (x) = x ^ 2 + 10x + 25 + 3x + 15 - 4
 f (x) = x ^ 2 + 13x + 36
 Equaling zero we have:
 x ^ 2 + 13x + 36 = 0
 We look for the roots of the polynomial:
 (x + 9) (x + 4) = 0
 x1 = -9
 x2 = -4
 Answer:
 
The zeros of the new function are:
 
x1 = -9
 
x2 = -4

The point (-2, 5) is not included in the solution area

<h3>The graph of the inequalities</h3>

The system of inequalities is given as:

y > 5x + 5

y > -2x+1

See attachment for the graph.

Since the inequalities use the greater than symbol, then the lines of the inequalities would be a dotted line and the upper part would be shaded

<h3>The solution area</h3>

The point is given as:

(-2, 5)

The point (-2, 5) is not in the shaded area of the system of inequalities

Hence, the point is not included in the solution area

Mathematically, we have:

5 > 5 * -2 + 5 ⇒ 5 > -5 --- true

5 > -2 * -2 +1 ⇒ 5 > 5 --- false

Since both inequalities are not true, then the point is justified
