simply need to fill in Y=Mx+b!
slope is 1/2, the and b (the y intercept) is 0! so y=1/2x + 0 or y=1/2x :)
We are given the exponential expression f(x) = Ca^x that should pass through the points (0,4) and (3,32). In this case, we first substitute the first point, (0,4) to the function to yield 4 = Ca ^0; hence Ca is equal to 4. The final expression hence is f(x) = 4^x
The answer that is NOT the formula for an area of a rectangle is A= 1/2X h X (Base 1 + Base 2)
The first and third graphs are both negative, so we can rule them out. Also, the fourth graph has no correlation, so we can rule that out. That leaves us with the final and correct answer, graph B.
Hope this helps!
