Answer:
slope is 2
Step-by-step explanation:
Answer:the slope is 5
Step-by-step explanation: your slope is always next to your x remember the formula mx+b=y in this case m = slope and b=y intercept so 5 is your slope :)
Answer:
f(g(x)) = 9
Step-by-step explanation:
Given f(x) =x-7 and g(x)= x^2 find f(g(4))
To calculate composition, first calculate g(4).
<u>g(4) can be calculated by replacing x with 4 in the equation</u>
g(x) = x^2
g(4) = 4^2 = 16
To calculate f(g(4)), we have to replace x in equation with the value of g(4)
f(x) = x-7
f(g(x)) = g(x) - 7
f(g(x)) = 16 - 7
f(g(x)) = 9
I would never know the answer to this question
Answer:
f(4) = 24
Step-by-step explanation:
Plug in 4 for x in the equation:
f(x) = x² + 3x - 4
f(4) = (4)² + 3(4) - 4
Remember to follow PEMDAS. PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
and is the order of operation.
First, solve the power:
(4)² = 4 * 4 = 16
Next, multiply 3 with 4:
3 * 4 = 12
Next, combine the terms:
f(4) = 16 + 12 - 4
f(4) = (16 + 12) - 4
f(4) = 28 - 4
f(4) = 24
f(4) = 24 is your answer.
