The graph of f(x) shown below resembles the graph of g(x)=2 but it has been changed her mind which of the following could be the

equation of f(x)

Mathematics

Tcecarenko [31]4 years ago

Answer:

A

Step-by-step explanation:

cuz if you pay attention to the y coordinate on f(x) it's 4 instead of 1 as in g(x). this means that y-coordinate is multiplied to 4 therefore 4g(x) and it is vertically shifted up 1 unit and therefore  the equation would be

f(x) = 4g(x) + 1

as g(x) = x²

.:

f(x) = 4x² + 1

Find the limit............​
liubo4ka [24]

Answer: -\frac{9}{x^2}

====================================================

Work Shown:

\displaystyle \lim_{\Delta x \to 0^{+}} \frac{\frac{9}{x+\Delta x} - \frac{9}{x}}{\Delta x}\\\\\\\displaystyle \lim_{\Delta x \to 0^{+}} \frac{\frac{9x}{x(x+\Delta x)} - \frac{9(x+\Delta x)}{x(x+\Delta x)}}{\Delta x}\\\\\\\displaystyle \lim_{\Delta x \to 0^{+}} \frac{\frac{9x-9(x+\Delta x)}{x(x+\Delta x)}}{\Delta x}\\\\\\\displaystyle \lim_{\Delta x \to 0^{+}} \frac{9x-9x-9\Delta x}{x\Delta x(x+\Delta x)}\\\\\\

\displaystyle \lim_{\Delta x \to 0^{+}} \frac{-9\Delta x}{x\Delta x(x+\Delta x)}\\\\\\\displaystyle \lim_{\Delta x \to 0^{+}} \frac{-9}{x(x+\Delta x)}\\\\\\\displaystyle \frac{-9}{x(x+0)}\\\\\\\displaystyle -\frac{9}{x^2}\\\\\\

The trick here is to first simplify the expression so that the \Delta x term in the very lower denominator cancels out. This is to avoid dividing by zero. Once this division by zero error is avoided, we can replace the delta x term with 0 and evaluate the limit as \Delta x approaches 0 from the right or positive direction.

Evaluate -3.28 - (-4.4) + (-p) where p = 9.7.
ValentinkaMS [17]

Answer:

-8.58

Step-by-step explanation:

you take -3.28 and add it to 4.4 (because that double negative cancels out) and then take that (1.12) and subtract 9.7 from that and you get -8.58

*No Picture* Find all real zeros of the function y = 2x - 4 a. 2 b. (2, –4) c. −4 d. −2
anygoal [31]

Answer:

a

Step-by-step explanation:

The zeroes of a function are when y = 0 so we can write 0 = 2x - 4 so we have to solve for x and when we do so we get x = 2.
