A quadratic function and an exponential function are graphed below. Which graph most likely represents the quadratic function? graph of function t of x is a curve which joins the ordered pair 0, 1 and 1, 3 and 3, 27. Graph of function p of x is a curve which joins the ordered pair 0, 2 and 1, 3 and 3, 11 and 5, 27 and 6, 38 p(x), because an increasing exponential function will always exceed an increasing quadratic function until their graphs intersect t(x), because an increasing quadratic function will always exceed an increasing exponential function until their graphs intersect p(x), be

anyone?

OpenStudy (anonymous):

It looks like your options cut off, but just from the points given it looks like t(x) = 3^x and p(x) = x² + 2.

p(x), because an increasing exponential function will always exceed an increasing quadratic function until their graphs intersect t(x), because an increasing quadratic function will always exceed an increasing exponential function until their graphs intersect p(x), because an increasing exponential function will eventually exceed an increasing quadratic function t(x), because an increasing quadratic function will eventually exceed an increasing exponential function

OpenStudy (anonymous):

those are the options

OpenStudy (anonymous):

ok. I put up equations above. Which of those is the quadratic?

OpenStudy (anonymous):

umm idk

OpenStudy (anonymous):

exponential functions have the variable in the exponent → t(x) quadratic functions have x raised to the 2nd power → p(x)

OpenStudy (anonymous):

your answer is the one that calls p(x) a quadratic function

OpenStudy (anonymous):

so its c?

OpenStudy (anonymous):

@peachpi

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

can i ask you another?

A toy rocket was launched from the ground. The function f(x) = -16x2 + 192x shows the height of the rocket f(x), in feet, from the ground at time x seconds. What is the axis of symmetry of the graph of f(x), and what does it represent? x = 12; it takes 12 seconds to reach the maximum height and 12 seconds to fall back to the ground x = 12; it takes 12 seconds to reach the maximum height and 24 seconds to fall back to the ground x = 6; it takes 6 seconds to reach the maximum height and 6 seconds to fall back to the ground x = 6; it takes 6 seconds to reach the maximum height and 3 seconds to fall back to the ground
