1.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 = 2x^2 + 7
y = 5^(x-4)

2.for each function shown:
•name the starting point.
•explain how y changes as x increases.

function #1: y = 0.5 + 3x
function #2: y = 3(0.5)x

3.the points on the graph represent both an exponential function and a linear function.

a. complete this table by reading the values from the graph. estimate any function values that are less than one.

x -3 -2 -1 0 1 2 3
exponential function
linear function

b. at approximately what values of x do both the linear and exponential functions have the same value for y?
