Identify the vertex and axis of symmetry of the following quadratic function: f(x) = 3x^2 + 6x +15

vertex (options (3,15) (-1/2 6) (1,10) (-1,12)

Axis of symmetry (options (x=6) (x=1) (x=-1) ) (x=-1/2))

Δabc is dilated by a scale factor of 3 with the origin as the center of dilation to form δa′b′c′. the slope of is -1.2. the length of is p units, the length of is q units, and the length of is r units. the slope of is . the length of is units.

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
