Answer: a= x^2 + 4x
Step-by-step explanation:
length= x
width= x+4
area= length x width
area = x(x+4)
area= x^2 + 4x
hope this helps :)
What does x² look like? <em>goes to +∞ on the left and the right</em>
Well, x⁴ is an even exponent so it is has the same end behavior as x².
Answer: +∞
Answer:
y = -4x + 5
Step-by-step explanation:
This linear function can be represented through the slope-intercept form, or y=mx+b. You already know your m value, 4, which is your slope. From there you can plug in your coordinate into the y and x values to find your y-intercept, or b.
y = mx + b
-3 = -4(2) + b
b = 5
Then you put it all together to form the equation f(x) = -4x + 5
