What is the input value for which \(f(x)=0\)? Quels sont les antécédents de 0 par \(f\) ?
Remplacer \(x\) par 0 Plug in 0 for \(x\) = Plug in \(x=0\)
The range of a function The complete set of all possible resulting values of the dependent variable (\(y\)- usually)- after we have substituted the domain.
The graph of \(f\) passes through \((1-0)\) Le graphique de \(f\) passe par le point de coordonnées \((1\pv 0)\)
The slope The ratio of the vertical change between two points- the rise- to the horizontal change between the same two points- the run
The slope of a line passing through the points \((x_1- y_1)\) and \((x_2- y_2)\) is \(m=\dfrac{y_2-y_1}{x_2-x_1}\)
A line with a positive slope \((m > 0)\) A line which rises from left to right
A line with a negative slope \((m < 0)\) A line which falls from left to right
The slope intercept form of a linear function \(y=mx+b\) - \(m=\text{slope}\) - \(b=y−\text{intercept}\)

To graph the function \(f\) Tracer précisément la représentation graphique de \(f\)
The function \(f\) is differentiable /dɪfə'renʃieɪbl/ on \(\mathbb{R}\) La fonction \(f\) est dérivable sur \(\mathbb{R}\).
To differentiate /dɪfəˈrenʃieɪt/ the function \(f\) Dériver le fonction \(f\)
\(f'\) est la dérivée de la fonction \(f\) \(f'\) is the (first) derivative /dɪˈrɪvətɪv/ of the function \(f\)
\(y'=\dfrac{\text{d} y}{\text{d} x}\) is the derivative /dɪˈrɪvətɪv/ of \(y\) with respect to \(x\) La dérivée de \(y\) par rapport à \(x\)
\(f'(2)\) est la dérivée de \(f\) en 2 \(f'(2)\) is the derivative of \(f\) at 2/the derivative of \(f\) at \(x=2\)/the derivative of \(f\) at the point 2
\(f''\) est la dérivée seconde de \(f\) \(f''\) is the second derivative /dɪˈrɪvətɪv/ of the function \(f\)
\(f'(x)\) \(f\) dash \(x\) or the (first) derivative of \(f\) with respect to \(x\) or \(f\) prime of \(x\)
\(f''(x)\) \(f\) double-dash \(x\) or the second derivative of \(f\) with respect to \(x\) or \(f\) double prime of \(x\)
If \(y=f(x)\)- \(y\) is called The image of \(x\) under \(f\)
If \(y=f(x)\)- \(y\) is called- \(x\) is called A preimage /pri:ɪmɪdʒ/ of \(y\) under \(f\)
When talking about limits- \(0\cdot \infty\) is called An indeterminate /ɪndɪˈtɜːmɪnət/ form

The function is concave /kɒnˈkeɪv/ down La fonction est concave
The difference quotient of \(f\) is the average rate of change of \(f(x)\) over the interval \([x-x+h]\) Le taux d'accroissement de \(f\) entre \(x\) et \(x+h\)
