function g has a vertex at (2,4) and the parabola opens downwards.

which of the following statements is true?

a.
the y-intercept of function f is greater than the y-intercept of function g.
b.
the minimum of function f is at (-5,6).
c.
the minimum of function g is at (2,4).
d.
the y-intercept of function f is less than the y-intercept of function g.

D

Step-by-step explanation:

he vertex form f(x) = a (x - h)2 + k and of the standard form f(x) = a x2 + b x + c are presented with several examples and their detailed solutions.

We start with the graph of the basic quadratic function f(x) = x2, then we graph examples of quadratic functions in vertex form and then in standard form.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
