Evaluate −f(a) f(x)=−5x²+2x−1

1 answer:

5 0

$\bf f(x)=-5x^2+2x-1\implies f(a)=-5(a)^2+2(a)-1
\\\\\\
f(a)=-5a^2+2a-1
\\\\\\
-f(a)\implies -~[-5a^2+2a-1]\implies 5a^2-2a+1$

Answer:

132p

Step-by-step explanation:

if 7 pens cost 84 total then you need to find the cost of each to know how much 11 pens would cost in total

84/7=12

now you know it's 12 each so just multiply 12 by 11 and you know how much for 11 total!

12*11=132p

Given

$f(x) = \begin{cases} -x^2 - 1 & \text{if }x \neq 5 \\ -3 & \text{if }x=5 \end{cases}$

we have

$\displaystyle \lim_{x\to5} f(x) = \lim_{x\to5} (-x^2-1) = -5^2-1 = \boxed{-26}$

since we are approaching $x=5$ , so effectively $x\neq 5$ and we use the definition of $f(x)$ under that condition.
