Answer:

  • quadratic function
  • y-intercept:  y = -6
  • x-intercepts:  x = 2 and x = 6
  • y = 2, x = 4
  • y ≥ 0

Step-by-step explanation:

The given graph is a <u>parabola</u> and so it a quadratic function.

The y-intercept is the point at which the curve <u>crosses the y-axis</u>.

From inspection of the graph, this is when y = -6.

The x-intercepts are the points at which the curve <u>crosses the x-axis</u>.

From inspection of the graph, the x-intercepts are x = 2 and x = 6.

The vertex is the <u>turning point</u> of the graph, so the <u>minimum point</u> of a parabola that opens <u>upwards</u>, and the <u>maximum</u> point of a parabola that opens <u>downwards</u>.

From inspection of the graph, the vertex is at (4, 2), so the greatest value of y is y = 2, and it occurs when x = 4.

The curve is <u>above the x-axis</u> between the interval x = 2 and x = 6.

Therefore, the function value is equal to zero or <u>positive</u> in this interval.

So the function value in the given interval is y ≥ 0.

Answer:

f(5) = 2

Step-by-step explanation:

it says to use the function (-x+3) for when x is bigger than 2

f(x) = (-x) + 3 replace x with 5

f(5) = (-5) + 3 and f(5) = 2

Points C and D lie on graph of the equation y = 1.3x.
deff fn [24]
Y = 1.3x

point C : (3,?)...so we sub in 3 for x and solve for y
y = 1.3(3)
y = 3.9
so point C is (3,3.9)

point D : (-6,?)...so we sub in -6 for x and solve for y
y = 1.3(-6)
y = -7.8
so point D is (-6,-7.8)

PLS HELP HURRY PLS!!

Answer:

(-2,-2)

Step-by-step explanation:

Step: Substitute 3x+4 for y in y=−x−4:

y=−x−4

3x+4=−x−4

3x+4+x=−x−4+x (Add x to both sides)

4x+4=−4

4x+4+−4=−4+−4 (Add -4 to both sides)

4x=−8

4x/4=−8/4(Divide both sides by 4)

x=−2

Step: Substitute −2 for x in y=3x+4:

y=3x+4

y=(3)(−2)+4

y=−2(Simplify both sides of the equation)
