Graph the functions and approximate an x-value in which the quadratic function exceeds the exponential function. y = 4^x and y = 7x^2 + 4x - 2

The quadratic function exceeds the exponential function for x<-0.924 and for x>0.53: (-Infinite,-0.924) U (0.53, Infinite).

Please, see the attached graph.

Thanks.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

5+2x=a
