Solution:

f(x) = 7(9 - x) - 4

f(-1) = 7(9 - (-1)) - 4

f(-1) = 7(10) - 4

f(-1) = 70 - 4

f(-1) = 66

<h3>Given Function:</h3>

F(x) = 7(9-x)-4

<h3>Value:</h3>

x = -1

f(-1)

<h3>Solution:</h3>

f(-1) = 7(9-(-1))-4

f(-1) = 7(9+1)-4

f(-1) = 7(10)-4

f(-1) = 70 - 4

f(-1) = 66

<h2>Answer:</h2>

f(-1) = 66

Answer:

A number cubed plus a 3 times a number squared all multiplied by 2 is equal to 4 times a number.

Step-by-step explanation:

Since we can't say "in parenthesis", we will have to say the expressions in the parenthesis first and then say "all multiplied by 2" to express parenthesis in word form. The rest are pretty straight forward.

What is the y-intercept of the exponential function? f(x)=−32(2)x−3+3 Enter your answer in the box.

Bogdan [553]

y-intercept for x = 0.

Substitute x = 0 to the equation of the function:

$f(x)=-32(2)^{x-3}+3\\\\f(0)=-32(2)^{0-3}+3=-32(2)^{-3}+3=-32\cdot\dfrac{1}{2^3}+3=-32\cdot\dfrac{1}{8}+3\\\\=-4+3=-1\\\\Answer:\ \boxed{y-intercept=-1\to(0,\ -1)}$
