Simple addition my dear friend. We know that Tina is 5 years older than John. So however old John is, if you ad 5 to that, you get Tina's age. So, 10 + 5 = 15. Tina is 15 years old.
You’re learning the definition of the derivative aren’t you. Just plug in x+h and do FOIL. Then multiply each term by -3 because of -3 infront of the square.
-3(x+h)^2 - 2(x+h) +4
-3[x^2 + 2xh + h^2] - 2x - 2h + 4
-3x^2 - 6xh - 3h^2 - 2x - 2h + 4
Your answer is D
Answer:
Step-by-step explanation:
The general equation for a parabola in vertex form is the following:
Where () is the parabola's vertex and (a) is the stretch and compression factor. As one can see in the given graph, the parabola has a vertex at (0, 1), moreover, it passes through the point (1, 3). Substitute these points into the equation for the parabole, and simplify,
Vertex: (0, 1)
A point on the parabola: (1, 3)
Inverse operations,
Substitute back into the original expression:
Simplify to put in standard form:
