Question

Use the graph to approximate the ordered pair where the exponential function begins to exceed the quadratic function.

the graph of an exponential function f of x equals two and two tenths to the power of x minus 7 tenths and a quadratic function g of x equals one eighth times x squared plus 2 times x plus 8

Answer 1

It's B (3.5, 17)

I don't know how that other guy got that but for me it's (3.5, 17) since I got it right.

Answer 2

(4.462, 19.411)

Explanation:

From the description, the functions are:

f(x) = (11/5)^(x - 7/10)

g(x) = 1/8x² + 2x + 8

(Notice that 2 2/10 is equivalent to 22/10 = 11/5)

In the picture attached, the plot of the functions is shown. The exponential is in red and the quadratic is in blue. The exponential function begins to exceed the quadratic function from point (4.462, 19.411)
