Mkey [24]3 years ago
7 0

Answer:

−3x^2-12x+63

Step-by-step explanation:

simplify-3(x-3) you should get -3x+9.

then use foil to get (-3x+9)(x+7)

you multiply -3x with (x+7) and tou should get (-3x^2-21x)

then multiply 9 with (x+7) and you should get (9x+63)

now you should have the numbers: -3x^2, -21x, 9x, and 63.

combine like terms: add 9x to -21x and tou will get -12x.

Now place the numbers in the correct order: variables with exponents, then nirmal variables, then non variables

On a coordinate plane, a curved line with a minimum value of (negative 2.5, negative 12) and a maximum value of (0, negative 3)
alekssr [168]

The points on the graph of (-4, 0), (-2.5, -12), and (0, -3), gives;

  • F(x) > 0 over the interval (-∞, -4)

<h3>Which method can be used to find the true statement?</h3>

From the description of the graph, we have;

Furthest point left of the graph = (-4, 0)

The furthest point right on the graph = (0, -3) = The maximum point

The minimum point = (-2.5, -12)

F(x) < 0 at the minimum point

The minimum point is to the right of x = -4

The point the graph crosses the y-axis = (0, -3)

Therefore;

The interval of the graph where F(x) is larger than 0 is to the left of (-4, 0), is the interval (-∞, -4)

The true statement is therefore;

  • F(x) > 0 over the interval (-∞, -4)
