Just set it equal to zero and solve using the quadratic equation.

The zeros of a function are when y = 0, so set the right side of the equation equal to 0. Then factor; the right side becomes (3x-2)(3x+4). Set both of those parentheses equal to zero to find the zeros, or roots, of the equation. 
x = 2/3, x = -4/3

If (42)^p = 41^4, what is the value of p?
babymother [125]

First you need to make both bases the same:

Lets remove the ^p and ^4

To make the base of 42 equal to 41, you would have 41^x = 41

X - ln(42) / ln(41) = 1.00648904


Now you have 41^1.00648904(p) = 41^4


Now the bases are equal so we need to set the exponents to equal:

1.00648904(p) = 4

Divide both sides by 1.00648904 to solve for P

P = 4 / 1.00648904

P = 3.97421114

Select the correct answer.<br> Which graph shows the solution region of this system of inequalities?
ELEN [110]

Since the values on both sides are different, hence graph of option C is correct.

<h3>What is inequality?</h3>

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Solutions to inequality graphs

Inequalities are an equation that does not include only the equal sign.

The system of inequalities are;

y \geq 2(1.3)^x\\\\y\leq -x^2 + 4x + 5

The first function is an exponential function.

Since the values on both sides are different, hence graph of option C is correct.
