Answer:
a) domain: (0, ∞)
b) range: (-∞, ∞)
c) increasing everywhere
d) concave downward
Step-by-step explanation:
a) Your knowledge of the log function tells you it is defined for positive arguments. 9x > 0 means x > 0. The domain is all positive real numbers.
__
b) Your knowledge of the log function tells you it has output values ranging from -∞ to +∞. The range is all real numbers.
__
c) The function is monotonically increasing.
__
d) Since the output does not increase as fast as the input (the first derivative is decreasing), the function is concave downward.
Answer:
27
Step-by-step explanation:
a 76 le quitas la diferencia de 22 y da 54 que lo divides entre 2 y da 27 por lo que 27+27=54+22=76
Answer:
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A quadratic function is given to us.
- The function is -3(x-1)(x-6)
And we need to find out the zeroes of the quadratic function and we need to express it in Standard form. T
<u>Function</u><u> </u><u>:</u><u>-</u><u> </u>
- So for finding the zeroes equate it with 0 .So that ,
<u>Therefore</u><u> the</u><u> </u><u>zeroes</u><u> </u><u>are </u><u>1</u><u> </u><u>and </u><u>-</u><u>6</u><u> </u><u>.</u>
<u>Expressing</u><u> </u><u>in </u><u>Standard</u><u> form</u><u> </u><u>:</u><u>-</u><u> </u>
The standard form of a quadratic equation is ,
And that of a quadratic function is ,
<u>Simplifying</u><u> the</u><u> </u><u>equation</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence</u><u> the</u><u> </u><u>Standard</u><u> form</u><u> of</u><u> </u><u>the</u><u> </u><u>equation</u><u> is</u><u> </u><u>-3x²</u><u> </u><u>-</u><u> </u><u>1</u><u>5</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u><u>8</u><u> </u><u>.</u><u> </u>
Answer:
110 degrees
Step-by-step explanation:
The three angles of any/all triangles should add up to 180
180 - 28 - 42 = 110
