Answer:
The value of f(-4) = -80
Step-by-step explanation:
It is given that, f(x) = -5x²
<u>To find the value f(-4)</u>
Let f(x) = -5x²
To find the value of f(-4), substitute -4 instead of x
f(-4) = -5 * (-4)²
= -5 * 16 [ since (-4)² = -4 * -4 = 16 ]
= -80
Therefore the value of f(-4) = -80
Simplify the given expression as shown below
7+8+9=24
second integer is 8 so 8*3=24
im pretty sure its the 2nd one!
