Answer: do your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!
<u>ANSWER</u>
Only the equation is a function
<u>EXPLANATION</u>
is graphed above with its inverse
.
We perform the vertical line test for both the equation and its inverse.
The equation
passed the vertical line hence it is a function.
However,
failed the vertical line test, hence it is not a function.
Can't see the graph can you make it more clear?
It looks like ∆ is defined as
<em>a</em> ∆ <em>b</em> = (<em>a</em> + <em>b</em>)² + 5
If that's the case, then
1 ∆ (-4) = (1 + (-4))² + 5 = (-3)² + 5 = 9 + 5 = 14
Well it depends. what the problem
