Suppose y varies directly with r ify=-4 when x=8, what is the equation of direct variation?
complete the steps to write the equation of direct variation.

answer:

x² + x + 2

step-by-step explanation:

to find (f + g)(x), you add f(x) and g(x).

        f(x) = x²       + 3

      g(x) =       x -   1

(f + g)(x) = x² + x + 2

answer:

i think the answer is 28ft 12in. sorry if im wrong, but let me know if i am

step-by-step explanation:

answer:

the graph of an exponential function of the form y = f(x) = aˣ passes through the points (0, 1) and (1, a). the graph lies above the x-axis.

step-by-step explanation:

the given function is

put x=0 in the given function,

put x=1 in the given function,

therefore graph of an exponential function of the form y = f(x) = aˣ passes through the points (0, 1) and (1, a).

it is an positive exponential function, therefore the value of function will always remains positive. so, the graph lies above the x-axis.
