A property of inverse functions is that if f(x) = a, g(a) = x
F(x) = (5x+1)/x
G(x) = x/(5x+1)
Plug in x = 3.
F(3) = 16/3
G(16/3) = 16/83. Since it doesn’t equal 3, it’s not an inverse function
Answer:
Time in seconds when the ball is 4 feet above the ground is:
t= 0.6 and 2.9.
Answer:
<em>$</em><em>1</em><em>0</em><em>9</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>difference</em><em> </em><em>between</em><em> </em><em>both</em><em> </em><em>the</em><em> </em><em>bills</em>
Step-by-step explanation:
<em>Difference</em><em> </em><em>=</em><em>$</em><em>(</em><em>3</em><em>0</em><em>3</em><em>-</em><em>1</em><em>9</em><em>4</em><em>)</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>$</em><em>1</em><em>0</em><em>9</em>
<em>Hope</em><em> </em><em>this</em><em> </em><em>helps</em>
88/100 can be simplified. Divide both sides by 4 which turns it into 22/25.
Grace got 22/25 questions correct.
The x intrercepts is where the function crosses the x axis; In other words, it is where the output of the function is 0.
In a quadratic, you can start by factoring, if it’s unable to be factored then use the quadratic formula. Also, it is good to use the discriminate.
D= Discrimminate
D>0 2 real solutions
D=0 1 real solution
D<0 2 imaginary solutions.
The discrimminate is the equation/expression under the radical of the quadratic formula. With this formula, it’s not factorable. Using the discriminate it is also seen, as you’ll get a negative in the square root. This is imagenary because you cannot take the root of a negative value, which is why “i” is used to represent the square root of negative one.
