What is the value of the expression f(–3)? -15 3 -3 15

arlik [135]

Answer:

Option A, -15

Step-by-step explanation:

Step 1: Look at the function that needs to be outputted when x = -3

Since x = -3, that means it falls into the first category of x ≤ -3

Step 2: Carry out the instructions

The function for the first category is $-x^{2} + 2x$

$f(-3) =-(-3)^{2}+2(-3)$

$f(-3) = -(9) - 6$

$f(-3) = -15$

Answer: Option A, -15

The temperature at 6:00 A.M. 58 degrees Fahrenheit. The temperature increased at a constant rate of 3 degrees Fahrenheit every h

Tasya [4]

Answer: $c. (t:58\leq t\leq 70)$

Step-by-step explanation:

given data:

T = 58 degree Celsius.

changes in temperature = 3dregres every hour = 4.

solution:

$t=58+3h\\where h = 4$

substitute the value for h into the equation.

$t=58+3(4)\\t=58+12\\t=70$

the set with $58\leq t\leq 70$ best represents the function range.
