Find f(4) if f(x)=−3x2+11x+37

amid [387]

Hi there!

$\large\boxed{f(4) = 33}$

f(x) = -3x² + 11x + 37

Substitute in 4 for x to find f(4):

f(4) = -3(4)² + 11(4) + 37

f(4) = -3(16) + 44 + 37

f(4) = -48 + 44 + 37

f(4) = 33

Elodia [21]

Answer:

The answer is B) 11.

Step-by-step explanation:

We can solve this by making an expression to represent the situation. Let x = the number of student books in the box (what we're looking for):

$2.3x + 4.3 + 0.4 = 30$

$2.3x + 4.7 = 30$

$2.3x + 4.7 - 4.7 = 30 - 4.7$

$2.3x = 25.3$

$2.3x/2.3 = 25.3/2.3$

$x = 11$
