Given the parent function f(x) = x², define the function g(x) that
Bas_tet [7]

Answer:

Part 1) g(x)=-x^{2}

Part 2) g(x)=(x+3)^{2}

Part 3) g(x)=x^{2}+7

Step-by-step explanation:

we have

The parent  function is f(x)=x^{2}

This is a vertical parabola open upward with vertex at origin (0,0)

Part 1) Reflection over the x-axis

The rule of the reflection across the x=axis is equal to

(x,y) ------> (x,-y)

so

f(x) -----> g(x)

The function g(x) will be

g(x)=-x^{2}

Part 2) Horizontal shift left 3 units

The rule of the translation is

(x,y) ------> (x-3,-y)

so

f(x) -----> g(x)

The function g(x) will be

g(x)=(x+3)^{2}

Part 3) Vertical shift up 7 units

The rule of the translation is

(x,y) ------> (x,y+7)

so

f(x) -----> g(x)

The function g(x) will be

g(x)=x^{2}+7

For F(x)=2x+1 and G(x)=c^2-7 find (FxG)(x)
Ludmilka [50]

The value of F(G(x)) is 2x^2 - 13

<h3>How to solve the composite functions?</h3>

The functions are given as:

F(x)=2x+1

G(x)=x^2-7

To find (FxG)(x), we make use of

(FxG)(x) = F(G(x))

So, we have:

F(G(x))=2G(x)+1

Substitute G(x)=x^2-7

F(G(x))=2(x^2-7)+1

Expand

F(G(x))=2x^2 - 14 + 1

Evaluate the like terms

F(G(x))=2x^2 - 13

Hence, the value of F(G(x)) is 2x^2 - 13

Which two triangles are congruent by ASA? Explain.
yarga [219]

Answer:

OGH and TCA

Step-by-step explanation:

that's quite easy...

the congruency criterion is ASA or Angle side Angle.

i.e. a side lying between two Angles.

so we have

GH = FN= CA

now, G=I= C

and H=N=A

it's pretty clear that G-GH-H = C-CA-A

(just to explain)

hence, the answer
