The area of a triangle is the product of the base of the triangle times the height of the triangle, divided by two.

Step-by-step explanation:

Almost correct.  I'd write this statement as follows:

"The area of a triangle is the product of the base and height of the triangle, divided by two."

or...

"The area of a triangle is half the product of the base and height."

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
