Find the x-intercept of the function f(x) = a^x + 1 - 1.
babymother [125]

I am not certain of what you wrote for the function but will assume that is likely exponential function or quadratic function.

First, (quadratic function) To solve this, you must know the quadratic formula. The x-intercept is value(s) that has the output value(y) of 0.

If the vertex of the quadratic function of (0,0), there is only one x-intercept. The number and value of the x-intercept depends on the slope and vertical displacement.

Second, (exponential function) note that there is no x-intercept. For instance, if a is 2, is there such value y that 2^y is 0? The smallest exponential value that is an integer is 1. Even broadening the limit to rational numbers, no such exponential value can have the result of 0. Therefore, in the basic form of exponential function, there is no x-intercept.

What is the solutions to 0=x^2-x-6<br> two things <br> ,,quadratic equationz,,,
natita [175]

Answer:

x1=3. x2=-2

Step-by-step explanation:

x =  \frac{ - b +  -  \sqrt{b {}^{2} - 4ac } }{2a}

b=-1

a=1

c=-6

x =  \frac{ - ( - 1) +  -  \sqrt{ {( - 1)}^{2} - 4 \times 1 \times ( - 6) } }{2 \times 1}

x =  \frac{1 +  -  \sqrt{1 + 24} }{2}

x =  \frac{1 + -   \sqrt{25} }{2}

x1 =  \frac{1 + 5}{2}

x2 =  \frac{1 - 5}{2}

x1=3

x2=-2

x =  \frac{1 +  - 5}{2}

Vijay has a collection of 50 number cubes that are each 1 cubic inch. He finds a box that is 4 inches high.He fits 12 cubes into
Lera25 [3.4K]

No, Vijay cannot fit all cubes into the box.

Solution:

Total number of cubes = 50

Volume of each cube = 1 cubic inch

Number of cubes fit in the bottom of the box = 12

Area of the box<em> = l</em> × <em>b</em> = 12 square inch

Height of the box = 4 inch

Volume of the box = <em> l</em> × <em>b </em>× h

                               = 12 × 4

Volume of the box = 48 cubic inch

So, 48 cubes can only fit in the box.

Hence, Vijay cannot fit 50 cubes into the box.
