Question

Graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. In your final answer, include a copy of the graph. y = 2x2 + 7 y = 5(x-4)

Answer 1

Answer:

x-value is 6.87

Step-by-step explanation:

we are given

Polynomial as

$y=2x^2+7$

Exponential as

$y=5^{x-4}$

Firstly, we can draw graph

We can see that intersection point is (6.87,101.392)

so, x=6.87
