The graph of a quadratic function meets the x-axis at the points (-4, 0) and (-2, 0). Given that the graph of the function also passes through the point (-8, 72), find the quadratic function in the...

Suppose you throw a ball straight up from the ground with a velocity of 180 ft per second. As the ball moves upward, Gravity slows it. Eventually the ball begins to fall back to the ground. The height...

In my 8th grade Advanced Algebra class, my group is moving extremely slowly due to constant chattering. I find it frustrating and would like to have the math skills to go into Advanced Geometry next...

write the quadratic function the form f(x)=a(x-h)^2+k then, give the vertex of its graph quadratic function given: f(x)=3x^2+30x+74

What are the x intercepts? What is the y intercept? What is the vertex point? What was does the parabola open? What is the equation for the line of symmetry?

Suppose the graph of y=h(x) is a parabola with axis of symmetry x=5, with h(5)=0 and h(9)=10. Find the value of h(1).

The smyth family has three children and they want to frame their graduation pictures the pictures are 5 inches by 7 inches wuth 5 inch sides being mounted horizontally. The horizontal spaces between...

Find the set of values for k for which the line y=2x−k meets the curve y=x2+kx−2 at two distinct points. I only know you have to use a discriminant. :/

A toy rocket is launched from the top of a building 55 feet tall at an initial velocity of 242 feet per second. a) Give the function that describes the height of the rocket in terms of time t b)...

stuart bikes 36 mi, averaging a certain speed. The return trip is made at an average speed that is 3mph slower. The total time for the round trip is 7hr. Find stuarts average speed on each part of...

Can you please describe when the ball will be at a height of 3 feet after it is thrown?

Okay so I have this question where they give me a graph and ask me to find out specific questions. My equation for this graph given is y=-x2-2x+3 It ask for the vertex...

My math homework says "Write an equation for a quadratic function whose graph satisfies the given condition. Use whatever form is most convenient." Number 5 says : Has y-intercept...

How would you write the quadratic function y = -3x² + 18x - 2 in vertex form? You'll need to calculate the vertex to find "h" and "k", and you'll need to use the value of "a"...
