Answer:

Range of f={-4,-3,0,5,12,21,32,...}

Step-by-step explanation:

We are given that a function

f(x)=x^2-4

We have to find the range of f.

Substitute x=2 then we get

f(2)=(2)^2-4

f(2)=4-4=0

When we substitute x=0 then we get

f(0)=(0)^2-4=0-4=-4

When we substitute x=1

f(1)=1-4=-3

When x=3

f(3)=(3)^2-4=9-4=5

Therefore, the range of f={-4,-3,0,5,12,21,32,...}

Answer:

a =7.5

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+ b^2 = c^2  where a and b are the legs and c is the hypotenuse

a^2 + 10 ^2 = 12.5^2

a^2 + 100  =156.25

Subtract 100 from each side

a^2 = 56.25

Take the square root of each side

sqrt(a^2) = sqrt( 56.25)

a =7.5

Let f(x)=g(x)h(x), g(10)=-4, h(10)=560, g'(10)=0, and h'(10)=35. find f'(10)
Ulleksa [173]
This question has extraneous info to trick you.
f(x) = g(x)h(x) ⇒ f'(x) = g'(x)h'(x) . Letting x = 10, we get f'(10) = g'(10)h'(10). then just plug in the values provided. g(10) and h(10) are there to throw you off, just use g'(10) and h'(10).
So f'(10), pronounced "eff prime of ten", = 0 * 35 = 0.

If the question were asking for f(10) instead of f'(10) then you would use g(10) and h(10), ⇒-4*560=90.
